nginx ignition has ParseAcceptLanguage `_` separator bypass that enables ~75x CPU amplification via Accept-Language header in i18nMiddleware

Summary The gin i18n middleware in nginx-ignition's API server runs in front of every HTTP request and calls golang.org/x/text/language.ParseAcceptLanguage on the raw Accept-Language header without imposing any size or shape filter. The underlying parser has quadratic-time behaviour on long lists...

nginx ignition has TOTP Reuse During Validity Window

Summary Any user that has enabled the OTP 2FA can have their TOTP reused during the standard 30 second validity window. Details The https://github.com/pquerna/otp package doesn't include checking for already used TOTPs within its the validity window. This requires each application that uses the...

k8saudit shipped rules do not detect privileged/sensitive settings on init or ephemeral containers

The k8saudit plugin's per-container fields ka.req.pod.containers. and the shipped k8sauditrules.yaml evaluated only requestObject.spec.containers. Security-relevant settings on a pod's initContainers or ephemeralContainers were not inspected, so the shipped Create Privileged Pod rule did not fire...

Hatchet - Unauthenticated OAuth state CSRF / login-CSRF via empty-state collision in ValidateOAuthState

Summary Hatchet version v0.86.26 and below is vulnerable to OAuth state CSRF login CSRF / account fixation. The vulnerable code clears the session oauthstate value to the empty string "" after a successful OAuth callback rather than removing the key, and the subsequent state-equality check then...

Duplicate Advisory: hono/jsx renders plain strings unescaped in boundary components, leading to XSS

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-hxh3-vqpv-xpqv. This link is maintained to preserve external references. Original Description hono before 4.13.7 fails to HTML-escape plain strings rendered by hono/jsx as a child or fallback of Suspense, as a...

http-cache-semantics max-stale handling can disclose cross-user cached responses

http-cache-semantics through 4.2.0 fails to properly validate security-zeroed cache entries when processing client max-stale directives, allowing unauthenticated attackers to retrieve cached responses belonging to other users. Attackers can request the same URL with a large max-stale value to...

braces vulnerable to stack-exhaustion denial of service through deeply nested patterns

braces through 3.0.3 contains a stack overflow vulnerability in the recursive AST walkers that lack depth guards. Attackers can supply deeply nested brace patterns under the character limit to exhaust the call stack and terminate the Node.js process with an uncaught RangeError...

Obot: Server-Side Request Forgery via remote MCP server URL

Summary In affected versions, the URL of a remote MCP server is attacker-controlled at registration and is fetched server-side with no validation of the destination. There is no guard against loopback, link-local, RFC1918 private ranges, or the cloud metadata endpoint 169.254.169.254, so a use wi...

Obot: MCP Registry API readable without authentication

Summary In affected versions, enabling registry authentication OBOTSERVERENABLEREGISTRYAUTH=true does not actually protect the MCP Registry endpoints under /v0.1/ — they remain readable by unauthenticated callers. Am I affected? You are affected if you run Obot = v0.22.1 with...

Obot: OAuth Dynamic Client Registration Enables API Token Theft via Audience Confusion

Summary In affected versions, an unauthenticated attacker could register an OAuth client with an arbitrary external redirect URI, and the authorization flow would auto-complete without a consent screen. If a logged-in victim visited a crafted authorization URL, an authorization code was delivered...

Paymenter has a credit-refund double-spend race condition in service downgrade (doUpgrade)

Summary The service downgrade implementation in app/Livewire/Services/Upgrade.php::doUpgrade executes a proration calculation and a subsequent user credit refund without any transactional safety or database locks. The only concurrency check relies on an unisolated database query checking for...

io.moquette:moquette-broker has a Missing Authorization issue

Summary Moquette MQTT Broker fails to enforce ACL write permission checks when publishing Will Last Will and Testament messages on behalf of disconnected clients. All normal PUBLISH paths receivedPublishQos0, receivedPublishQos1, receivedPublishQos2 correctly invoke authorizator.canWrite before...

Mnemosyne has JWT signature verification bypass sync server that allows authentication bypass

Summary The Mnemosyne sync server's authentication check decoded JWT bearer tokens but never verified their HMAC-SHA256 signatures. Any well-formed token was accepted, allowing an unauthenticated attacker to impersonate any user and read or modify their sync data. Severity: Critical CVSS 3.1:...

Perses's unvalidated project parameter enables filesystem path traversal

Impact When Perses is using the file system database, on the list endpoints, the project value is bound from the request into the resource Query struct and is never validated against directory-traversal characters validation/Flatten only runs for Create/Update bodies, not list queries. The path i...

Perses's missing authorization in datasource proxy allows cross-scope secret disclosure

Impact The datasource proxy authorizes the caller on the Datasource scope, then resolves and decrypts any Secret named in the request body with no Secret-scope check. Datasource and Secret are distinct, independently grantable role scopes, so an operator can grant datasource access without secret...

Perses's project query parameter authorization bypass exposes cross-project resources

Impact What kind of vulnerability is it? An authenticated user who is only a viewer on project team-a requests GET /api/v1/projects/team-a/dashboards?project=finance-secret or simply GET /api/v1/datasources?project=finance-secret and receives the full list of the finance-secret project's dashboar...

File Viewer: DOM XSS via unsafe hyperlink schemes in the legacy DOC renderer

Summary Before 2.3.1, the legacy .doc renderer emitted document hyperlink targets after HTML escaping but without a URL-scheme allowlist. A crafted .doc could therefore render a live javascript:, vbscript:, data:, or similarly unsafe link. Script could execute in the embedding origin if a viewer...

adm-zip: Uncontrolled memory allocation via the declared uncompressed size (DoS)

Summary adm-zip allocates an entry's output buffer from the declared uncompressed size central-directory size field before validating it against the actual data. A tiny crafted ZIP that declares a huge uncompressed size forces a multi-gigabyte allocation from a few bytes. Impact On adm-zip 0.5.17...

Process Compose: Browser DNS rebinding lets websites control local process-compose MCP tools

Summary A malicious website can use DNS rebinding to control a developer's local process-compose MCP SSE listener when MCP SSE is enabled. The vulnerable path accepts browser-origin requests before any Host validation, Origin validation, or caller-secret check, then dispatches the requests into...

Convoy: Cross-Tenant Source IDOR Leaks Plaintext Message Broker Credentials

Summary frain-dev/convoy all versions up to and including v26.6.2, no patch available lets any authenticated caller who is authorized on at least one project read ANY OTHER project's "Source" record by ID via GET /api/v1/projects/projectID/sources/sourceID -- regardless of whether that Source...

md-editor-v3: XSS via fenced-code language rendering bypass

Summary MdPreview interpolates a fenced-code language into HTML attributes without escaping it. A crafted info string therefore executes JavaScript even when the shipped XSSPlugin is enabled. Details useMarkdownIt packages/MdEditor/layouts/Content/composition/useMarkdownIt.ts:206 registers a...

AnyCable: Telemetry Subsystem Contains Hardcoded Authentication Token and Transmits CLI Arguments Including Secrets

Summary The telemetry subsystem embeds a hardcoded auth token "secret" in the public source and transmits raw CLI arguments—including --secret, --jwtsecret, and --httprpcsecret values—to a third-party telemetry endpoint. Details In telemetry/config.go line 12, var authToken = "secret" is committe...

AnyIO run_process/open_process ignores extra_groups and can retain parent supplementary groups

AnyIO 4.14.0 accepts the POSIX extragroups argument on anyio.runprocess and anyio.openprocess, but openprocess forwards the wrong variable to the backend: when extragroups is not None, it assigns kwargs"extragroups" = group instead of extragroups. As a result, callers cannot reliably clear or set...

AnyIO: TLSStream IDNA 2003 host name encoding enables potential TLS certificate spoofing

Impact Services using internationalized non-ASCII domain names are potentially vulnerable to TLS connections made from AnyIO's connecttcp or directly via TLSStream.wrap where the connection has through other means been hijacked and redirected to a malicious server. The attacker would obtain a...

AnyIO process-pool workers can block indefinitely on undrained stderr

Impact AnyIO starts process-pool workers with stderr connected to a pipe but never drains that pipe. The worker redirects stdin and stdout to /dev/null to protect its protocol, but does not redirect stderr even though the documentation says all three standard streams are redirected. Worker code...

AnyCable: Pusher REST API Does Not Verify Request Body MD5 Enabling Signed-Request Replay with Arbitrary Body

Summary The Pusher-compatible REST API includes bodymd5 in the HMAC signature string but never computes or verifies the MD5 of the received HTTP body, allowing anyone who observes a signed request to replay it with an entirely different body. Details In pusher/http.go, the Handler function extrac...

ToolHive: containerized MCP servers can reach host services via host.docker.internal, enabling lateral movement

Summary A containerized MCP server running with the default network permission profile insecureallowall: true can reach host-local services via host.docker.internal. This includes the ToolHive API itself, other ToolHive-managed MCP server proxies, and any other service listening on the host's...

kcp front-proxy does not strip inbound X-Remote-* identity headers, allowing any authenticated client to inject groups/warrants and impersonate system:masters in any workspace

Summary The kcp front-proxy fails to strip client-supplied identity headers before forwarding requests to shards. Any authenticated tenant can inject their own X-Remote-Group and X-Remote-Extra- headers, which the shard trusts as a verified identity assertion — allowing a low-privilege user to...

zot: Bearer authentication maps DELETE to push scope, allowing unauthorized deletion

Summary A bearer token with only pull and push scopes can successfully delete manifests and blobs from a zot registry. The bearer authentication handler maps all non-GET/HEAD HTTP methods, including DELETE, to the "push" action, and the DistSpecAuthzHandler middleware is bypassed entirely for...

Capsule: hostnameRegexHandler.OnUpdate validates stale (old) Tenant regex, allowing invalid AllowedHostnames regex to bypass webhook validation

Summary A parameter order bug in internal/webhook/tenant/validation/hostnameregex.go causes the hostnameRegexHandler.OnUpdate webhook to validate the old Tenant object's AllowedHostnames.Regex instead of the new one being submitted. This allows an invalid malformed regex to bypass admission...

Capsule: Tenant owner bypasses Capsule's forbidden namespace/service/node label and annotation enforcement

Summary Capsule lets a cluster administrator forbid specific metadata keys that tenant owners must not place on their own resources: Tenant.spec.namespaceOptions.forbiddenLabels / forbiddenAnnotations namespaces, Tenant.spec.serviceOptions.forbiddenLabels / forbiddenAnnotations Services, and the...

Capsule: Malformed ForbiddenAnnotations.Regex can bypass Tenant validation and trigger namespace admission panic

Summary A validation bug in internal/webhook/tenant/validation/forbiddenannotationsregex.go allows an invalid ForbiddenAnnotations.Regex value to bypass Tenant admission on update. The webhook compiles ForbiddenLabels.Regex for both labels and annotations, so a malformed annotations regex can be...

LMDeploy has an SSRF bypass

Summary The URL checking logic in lmdeploy has a logical flaw that could be bypassed by attackers, leading to SSRF attacks. Details The current lmdeploy project uses issafeurl to validate the input URL. The main logic is to perform security checks on the host portion of the URL extracted by...

Summary lmdeploy = latest contains a code injection vulnerability in lmdeploy/pytorch/config.py line 620 that allows an attacker to execute arbitrary Python code by publishing a malicious HuggingFace model with a crafted quantizationconfig.quantdtype value. When a user loads the model with...

LMDeploy has Remote Code Execution by Pickle Deserialization via handle_zmq_recv in lmdeploy/lmdeploy/pytorch/disagg/conn/engine_conn.py

Summary LMDeploy's PyTorch DistServe/PD-disaggregation control plane used recvpyobj to deserialize messages received through a ZeroMQ PULL socket. PyZMQ implements recvpyobj using Python pickle deserialization, which can execute arbitrary code while reconstructing an object. The peer address used...

Semantic MediaWiki'a missing authorization in the smwtask API module allows unauthenticated access to admin-only maintenance tasks

Summary The api.php?action=smwtask API module performs no authorization check. The equivalent maintenance interface in the web UI Special:SMWAdmin requires the smw-admin right, but the API module that backs several of the same operations enforces nothing. An unauthenticated visitor can therefore...

Semantic MediaWiki's Special:FacetedSearch cstate hidden inputs enable reflected XSS (residual of CVE-2025-10354)

Summary Special:FacetedSearch cstate hidden inputs enable reflected XSS residual of CVE-2025-10354 Details Affected versions and vulnerable location - Confirmed present on latest shipped release tag available in the local clone: SemanticMediaWiki/[email protected]. - Confirmed present on...

Semantic MediaWiki affected by reflected XSS in `Special:Ask` via a forged cursor pagination token

Reflected XSS via a forged cursor pagination token Failure mode Special:Ask accepts a cursor query parameter for keyset pagination added in 7.0.0. The token is decoded by CursorEncoder, which is an unsigned base64url-encoded JSON blob, so its contents are fully attacker-controlled. When the...

Semantic MediaWiki has a query debug output XSS (`DebugFormatter`)

Query debug output XSS Failure mode Semantic MediaWiki's query debug output format=debug, or the debug request parameter on Special:Ask is assembled by SMW\Query\DebugFormatter and emitted as raw HTML. Several of its sinks apply no output-context encoding, so attacker-controlled query input is...

Semantic MediaWiki has an open redirect in Special:URIResolver

Failure mode Special:URIResolver resolves its user-controlled subpage to a MediaWiki title and issues an HTTP 303 redirect to $title-getFullURL without validating the resolved target. A crafted subpage can make that target point off-host: an interwiki prefix redirects to the foreign wiki for...

Semantic MediaWiki affected by Special:Ask table `sep` parameter reflected XSS

Failure mode sep was inserted verbatim into the HTML that joins a table cell's values. This made it possible to inject HTML through the separator value. The same unsanitised table HTML is produced both for the standard Special:Ask render and for its raw request output requesttype=raw, so the...

Semantic MediaWiki has reflected XSS in `Special:SearchByProperty` (`property` and `value` parameters)

Failure mode The value parameter was reflected back into rendered output and error messaging paths without enough output-context encoding. Remediation - The form value is escaped before it is placed back into the input field. - Derived error messages are also escaped before being rendered into...

Semantic MediaWiki has reflected XSS in Special:Ask plain table headers

Failure mode When headers=plain, table header text was emitted into via a raw HTML path. User-controlled mainlabel content could therefore become executable HTML. Remediation - TableResultPrinter now applies output-context escaping before passing plain headers to the table renderer. - The fix is...

Semantic MediaWiki vulnerable to stored XSS through wikitext via improper use of non-reserved data attributes

Summary The SemanticMediaWiki extension inserts the unsanitized value of a data attribute into the DOM as HTML, allowing for stored XSS through wikitext. Details In ext.smw.js, the data-subtab attribute of all elements with the smw-subtab class is parsed as JSON and appended to the innerHTML of t...

org.xwiki.rendering:xwiki-rendering-xml has an Eval Injection issue

Impact Any user who can edit their own user profile or any other document can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The reason is that rendering output is included as...

Opencast: Stored XSS in Paella player via WebVTT/DFXP caption cue text

Summary The Opencast Paella player renders caption cue text into innerHTML without escaping. The captions canvas clears captionsContainer.innerHTML and then appends each active cue with captionsContainer.innerHTML += cue, so HTML inside a WebVTT or DFXP cue becomes live DOM and executes in the...
