OpenChoreo: Unauthenticated build/workflow trigger via git-provider confusion (webhook signature bypass)

Summary The OpenChoreo autobuild webhook endpoint POST /api/v1alpha1/autobuild selected the git provider used to authenticate an incoming webhook from a client-supplied request header rather than from the target component's configuration, and its Bitbucket provider accepted requests without a val...

OpenChoreo: Cross-project command execution and wirelog view access via OpenChoreo openchoreo-api exec and wirelogs endpoints

Summary The OpenChoreo API server openchoreo-api authorized requests to its exec and wirelogs endpoints against the project supplied by the caller in the request, rather than against the project that actually owns the target component. The target component was resolved by name only, and the...

OpenChoreo: Unauthenticated access to data-plane operations via OpenChoreo cluster-gateway management APIs

Summary The OpenChoreo control-plane cluster-gateway served its caller-facing management APIs on the same network listener that accepts data-plane agent connections. In the multi-cluster topology that listener is published outside the cluster, and the management APIs did not authenticate the...

Mailpit: SMTP command parser buffers unbounded command lines before syntax rejection

Summary Mailpit's SMTP server reads each command line with an unbounded bufio.Reader.ReadString'\n' before parsing the command or enforcing any protocol length limit. A remote SMTP client can send an oversized single command line and force Mailpit to allocate attacker-controlled memory before the...

SeaweedFS: Filer JWT allowed_prefixes literal prefix match allows cross-tenant access to sibling paths

Impact When a filer JWT restricts a token to a set of path prefixes via allowedprefixes, the authorization check used a literal byte-prefix match strings.HasPrefix. A token scoped to /tenant1 therefore also authorized requests to sibling paths such as /tenant1234, /tenant1-old, and /tenant1backup...

Centrifugo: Client-forgeable headers emulation lets any client spoof headers forwarded to proxy backends

Vulnerability Details File: internal/client/handler.go OnClientConnecting, internal/proxy/http.go requestHeaders, internal/proxy/grpc.go requestMetadata, internal/unigrpc/grpc.go Consume Line: handler.go:389,548-552 e.Headers - SetEmulatedHeadersToContext, http.go:131-165 requestHeaders,...

Mailpit: Thumbnail generation decodes unbounded image dimensions before scaling

Summary Mailpit's thumbnail endpoint decodes attacker-supplied image attachments into a full raster before checking any decoded-pixel, dimension, or memory budget. A remote client that can store an email and reach the default web API can supply a compact high-dimension image, then request...

Scrapy: S3DownloadHandler sends signed S3 requests over plaintext HTTP by default

Problem Scrapy’s S3DownloadHandler sends signed S3 requests over plaintext HTTP by default. A normal request like s3://bucket/key is converted into http://bucket.s3.amazonaws.com/key unless request.meta"issecure" is explicitly set. The generated request is then signed with configured AWS...

DiceBear: SVG injection via the unescaped rotate option in @dicebear/core (and fontSize/fontWeight in @dicebear/initials)

Summary @dicebear/core builds avatar SVGs from caller-supplied options. The numeric rotate option is interpolated into an SVG transform attribute without XML-escaping. It is typed as a number, but nothing checks the type at runtime, so a string value passes straight through and can break out of t...

Omnigent Guardrail policy bypass: shell-command parser fails open in policies/builtins/_shell.py

Reporter: Aaron / Aeon — autonomous security agent https://github.com/aaronjmars/aeon Project: omnigent-ai/omnigent v0.1.0 Databricks — meta-harness running Claude Code / Codex / Pi "in check with policies and sandboxing" Component: omnigent/policies/builtins/shell.py shared parser → consumed by...

Plate: SSRF with response disclosure in DOCX image embedding

Summary @platejs/docx-io can fetch remote image URLs while converting HTML to DOCX. When an application converts attacker-controlled HTML in a server-side or privileged environment, this can cause the application environment to make unintended outbound requests and include fetched image data in t...

Handlebars.java: Arbitrary file read in `SpringTemplateLoader` via URL-fragment suffix bypass

Summary com.github.jknack.handlebars.springmvc.SpringTemplateLoader resolves Spring MVC view names into URLs via Spring's ResourceLoader without applying the path-containment check that protects every other URL-based loader in the project ClassPathTemplateLoader, FileTemplateLoader,...

Hurl: Cookies in Cookies section leak when redirecting to a different host

The Bug Hurl = 8.0.1 lets you define cookies two ways in a .hurl file: 1. As a raw Cookie: header in the Header/headers area 2. In a dedicated Cookies section parsed into RequestSpec.cookies When following a redirect to a different host, Hurl correctly strips security-sensitive data Authorization...

Mail: Email address spoofing via malformed RFC 2047 encoded-words

Summary Mail::Utilities.qvaluedecode and Mail::Utilities.bvaluedecode decoded only the first RFC 2047 encoded-word in a string and used an overly greedy pattern to match the charset token. A crafted, malformed encoded-word embedded in an address display name or local part could cause the decoded...

Grav: 2FA Bypass via 'login.regenerate2FASecret' - Secret Rotation During Pending Challenge

Summary When 2FA is enabled on an account, submitting correct credentials authenticates the user but leaves them unauthorized pending TOTP verification. During this pending-challenge window, the login.regenerate2FASecret task which requires only $user-exists, not $user-authorized can be called...

Omnigent: Unvalidated os_env.cwd in agent bundle yields arbitrary host filesystem access on runners without OMNIGENT_RUNNER_WORKSPACE

Summary An authenticated, non-admin user can obtain arbitrary host-filesystem read/write and host environment-secret disclosure on an Omnigent runner by uploading an agent bundle whose osenv.cwd points outside any intended workspace e.g. / or /home/. The cwd field is taken verbatim from the bundl...

Omnigent: Shared Agent Bundle Overwrite Leads to Authenticated Runner RCE

Summary An authenticated user with edit access to their own session can overwrite a shared/template agent by uploading a full agent bundle through PUT /sessions/sessionid/agent. Shared/template agents are shown as not MCP-editable, but this upload path still accepts a replacement bundle. By addin...

Omnigent: Uploaded Agent Bundle Allows Authenticated Runner RCE via Python Callable Tools

Summary An authenticated user can upload a crafted agent bundle that defines a server-side Python callable tool. The server validates the uploaded bundle, but it does not block dangerous callable: paths in untrusted user-provided agent configs. When the tool is invoked, the runner imports and...

Grav: Twig sandbox config exfiltration via grav.offsetGet + dump filter (CVE-2026-44738 bypass)

Summary The Twig content sandbox replaces config with the redacted SandboxConfig facade and strips Config::get/toArray from the method allowlist GHSA-j274-39qw-32c9, so editor content can't read config secrets via config. That's bypassable: grav is the raw container, offsetget is allow-listed on...

Grav: Decompression Bomb via ZipArchiver - Missing Extraction Limits

Summary ZipArchiver::extract lacks limits on uncompressed size, file count, and nesting depth, creating a distinct, unpatched variant of the GHSA-2vcx-h8p2-9pg9 zip bomb vulnerability. While the parallel method Installer::unZip received comprehensive limits, ZipArchiver::extract remains...

link-preview-js DNS Rebinding SSRF Bypass / Incomplete Fix for CVE-2026-43897

The existing advisory GHSA-4gp8-rjrq-ch6q / CVE-2026-43897 states that the SSRF issue was fixed in 4.0.1. However, 4.0.3 remains bypassable when the documented resolveDNSHost mitigation is used. Root cause: The library validates one resolved IP address through resolveDNSHost, but later performs...

fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

Impact fast-uri canonicalizes a host to its ASCII form only when the input carries an explicit scheme. When resolve resolves a scheme-relative reference //host/ against a scheme-bearing base, it still emits the host verbatim even though the effective scheme is known, so re-parsing the resolved UR...

fast-uri vulnerable to server-side request forgery via malformed IPv6 normalization

Impact fast-uri does not validate the complete RFC 3986 grammar for bracketed IPv6 literals, so a malformed literal with invalid trailing text is silently truncated to a different valid IPv6 address with no error reported. For example, normalize'http://::not-valid/private' returns...

fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding

Impact fast-uri decodes a hostname's percent escapes twice in a single normalize or resolve call: once during parsing and again during authority recomposition. A nested percent-encoded host therefore survives the first decode and is turned into a live destination by the second, so...

fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

NLTK: Default ENFORCE=False Disables All pathsec Security Controls

NLTK's pathsec.py security module defaults to ENFORCE=False line 24, which means all 8 security validation functions only emit RuntimeWarning instead of raising exceptions when violations are detected. The pathsec module was introduced as the fix for CVE-2024-39705 arbitrary code execution via...

NLTK: SSRF Fail-Open in validate_network_url() via DNS Resolution Failure

There is an SSRF vulnerability in NLTK 3.9.4's network URL validation. The validatenetworkurl function in nltk/pathsec.py fails open when DNS resolution returns an error. The resolvehostname helper at lines 193-234 catches OSError and ValueError during socket.getaddrinfo and returns an empty list...

xmldom: XML fragment injection via invalid EntityReference.nodeName during requireWellFormed serialization

Summary An EntityReference node can be created with an invalid, attacker-controlled name through Document.createEntityReferencename. When this node is serialized directly with: js serializer.serializeToStringref, requireWellFormed: true the invalid nodeName is emitted into the serialized XML...

Mistune: Denial of Service — RecursionError via Excessive Emphasis Markers in Markdown

Summary Mistune v3.3.2 is vulnerable to a Denial of Service DoS attack via uncontrolled recursion in the HTML rendering of deeply-nested emphasis tokens. By submitting Markdown containing approximately 1,000 consecutive asterisk characters, an attacker causes the Python process to crash with...

fastify vulnerable to X-Forwarded-* spoofing under trustProxy hop-count

Impact The fix for CVE-2026-3635 GHSA-444r-cwp2-x5xf added a proxyFnsocket.remoteAddress, 0 guard on the X-Forwarded- reads in request.host, request.protocol, request.hostname, request.ip, and request.ips. That guard closes the IP, CIDR, and custom-function forms of trustProxy correctly because...

fastify vulnerable to schema validation bypass via root primitive coercion mismatch

Impact fastify before 5.12.1, when a route uses a root-level primitive body schema for example an integer with a minimum and maximum and the default type coercion, validates the coerced value but exposes the original, uncoerced value to the route handler. For example, a JSON body "10" is coerced ...

ApostropheCMS: 2nd-order prototype pollution via PATCH leading to single-request persistent DoS

The vulnerability is a single-request persistent DoS by submitting e.g. "PATCH /api/v1/article/" with a valid editor session and body of "toString.call":"x", overwriting the global toString function with value x. Fabian...

Sulu: Stored XSS via media download inline-disposition override

Impact Stored Cross Site Scripting XSS in the media download endpoint. The download route /media/id/download/slug and its admin variant accepts the query parameter ?inline=1. When it is present, the response is sent with the header Content-Disposition: inline for any MIME type, which overrides th...

Sulu: Fix authorization bypass when creating preview links

Impact A missing authorization check on the preview link endpoint lets a backend user create a public, unauthenticated preview URL for content they are not allowed to see. PreviewLinkController and the underlying PreviewLinkManager::generate / revoke never enforced a permission on the target...

Sulu: Media move/update authorization bypass (IDOR)

Impact A media move authorization bypass IDOR lets a backend user move a media out of a collection they have no access to. The media move endpoint resolves its permission check from the collection value in the request rather than from the media's real collection. MediaManager::move then reassigns...

ApostropheCMS: Arbitrary file read via import-export attachment-name path traversal

Summary The @apostrophecms/import-export module reconstructs the on-disk source path of every imported attachment from JSON metadata contained in the uploaded archive. The archive carries an aposAttachments.json file whose name and extension fields are concatenated into a filesystem path with no...

Kirby: Access to image files outside of the site root via path traversal in the media handling

TL;DR This vulnerability affects all Kirby sites that are deployed in a way that their index root on the server is next to a second directory that is read-accessible to PHP and shares the same name prefix such as the site with the index root /var/www/site being next to /var/www/site2. It was...

Orval: Generation-time SSRF + remote/local file inclusion via unrestricted $ref

Summary Orval resolves OpenAPI $refs by fetching remote https URLs and reading local files including absolute / out-of-tree paths, inlining the referenced schema into the generated client. Running orval on a spec whose $ref points at an attacker/internal URL or an arbitrary local file yields SSRF...

Orval: Import-time RCE via query-parameter default -> zod module-level template literal

Summary Orval's zod schema generation emits the query-parameter default value as a module-level template literal export const …Default = ; without escaping $ or the backtick. A default of the form v$w injects a live JavaScript expression evaluated when the generated zod schema module is imported,...

Orval: Import-time RCE via schema property name -> computed-property-key injection in the zod client

Summary orval's zod client emits each schema property name as a double-quoted key in the generated zod.object... WITHOUT escaping the double quote. A " in a property name closes the key and lands in object-literal context, where an injected computed property key expr is evaluated when zod.object...

CKAN MCP Server: MQA server allowlist bypass via unanchored regex (`isValidMqaServer`)

Summary The ckangetmqaquality and ckangetmqaqualitydetails tools restrict their serverurl argument to dati.gov.it via a regular expression. The regex is anchored only at the start and places no boundary after the host, so any URL whose host merely begins with dati.gov.it — or that uses dati.gov.i...

SeaweedFS: Unauthenticated filer IAM gRPC service grants S3 administrative control

Impact The filer registered the IAM gRPC service SeaweedIdentityAccessManagement with no authentication. Any client able to reach the filer gRPC port could invoke IAM RPCs — CreateUser, CreateAccessKey, PutUserPolicy, and related calls — to mint credentials and grant itself S3 administrative...

Grav: Remote code execution via unrestricted callable in Blueprint::dynamicData()

Summary An account with the admin.pages permission or api.pages.write can run shell commands on the server. The command executes whenever anyone — including an unauthenticated visitor — opens the page. Details Blueprint::dynamicData system/src/Grav/Common/Data/Blueprint.php:426 passes a...

Grav: Authenticated ReDoS via regex_replace in Twig Sandbox

Summary The regexreplace filter and function are allowlisted in Grav's Twig content sandbox. When Twig processing in page content is enabled security.twigcontent.processenabled: true, authenticated page editors can supply a catastrophically backtracking PCRE pattern, causing unbounded CPU...

qs array-limit bypass via bracket-key comma parsing

Summary qs v6.15.3 allows bracket-key input to bypass arrayLimit and throwOnLimitExceeded when comma: true. The input a=1,2,3,4 succeeds with arrayLimit: 3, while the equivalent plain-key input is rejected. Affected version tested: text qs v6.15.3 commit 18d085e919dae70c8f1b200ab99323058edab2c2...

qs: Denial of Service via Attacker Controlled isBuffer

Summary qs.stringify calls utils.isBuffer on every value it serializes, and utils.isBuffer invokes obj.constructor.isBufferobj without checking that it is callable. A value whose own constructor.isBuffer is a non-function makes qs call a non-callable and throw TypeError. Such a value is produced ...

Tiptap: mergeAttributes() turns an own __proto__ key into inherited executable DOM attributes

Summary @tiptap/core's public mergeAttributes helper uses ordinary bracket assignment on keys returned by Object.entries. An own proto key from JSON therefore invokes the legacy prototype setter on the fresh merged object. The function returns an object whose prototype is attacker-controlled, whi...

EasyAdmin custom-action dispatcher bypasses access_control on other routes

Summary EasyAdmin serves all backend requests through a single dashboard route and, for custom actions Action::linkToRoute / MenuItem::linkToRoute, swaps the executed controller based on the routeName query parameter on the kernel.controller event. That swap happens after Symfony's security...

Livewire DOM-based cross-site scripting during client-side state handling

Impact In Livewire v3 ≤ 3.8.2 and v4 ≤ 4.3.3, a vulnerability allows unauthenticated attackers to execute arbitrary JavaScript in the origin of an affected application in specific scenarios. The issue stems from how certain client-side component state is handled. This vulnerability does not affec...

Tornado: Urlencoded body parsing omits max_num_fields, so one request can stall the event loop

Summary Tornado parses application/x-www-form-urlencoded bodies with urllib.parse.parseqs and does not pass maxnumfields. A body made almost entirely of separators produces tens of millions of fields, and the parse happens on the event loop before the handler runs, so a single request stalls the...
