Gitea: Remote Code Execution via diffpatch Git Hook Installation

Gitea's diffpatch endpoint can be abused to install and execute a Git hook from repository-controlled content. An attacker with ordinary write access to a repository can execute arbitrary shell commands as the Gitea OS user. With default open registration, an unauthenticated visitor can obtain th...

CKAN MCP Server: Cache-key canonicalization collision enables cache confusion / poisoning

The response cache derives its key from an ambiguous string serialization of the request parameters. canonicalizeParams joins sorted $key=$value pairs with & and does not escape &, =, or the | field separators used in buildCacheKey. Two different logical parameter sets can therefore serialize to...

CKAN MCP Server: Information disclosure via verbose error reflection

Error paths reflect raw upstream response bodies and internal exception messages back to the caller instead of a sanitized, generic message. When the server is pointed at or redirected/SSRF'd to a host that returns a non-CKAN response, or when an internal exception occurs, the caller receives...

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

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.it as URL...

9router: Unauthenticated LLM proxy access via /codex rewrite authorization bypass

9router exposes an OpenAI/Anthropic-compatible LLM proxy. Remote access to this proxy is intended to be protected by an API-key check in the Next.js middleware. However, 9router also defines a rewrite that maps /codex/ to the backend LLM endpoint /api/v1/responses. The middleware authorization...

9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

9router's request guard decides a request is "local" and therefore exempt from API-key auth on the /v1 LLM proxy by reading the client-controlled Host header. Because 9router binds 0.0.0.0 by default and the CLI misleadingly prints "localhost", a remote, unauthenticated attacker who can reach the...

9Router: Authenticated Server-Side Request Forgery (SSRF) via OIDC Provider Test Endpoint

A Server-Side Request Forgery SSRF vulnerability exists in the 9Router dashboard via the /api/auth/oidc/test endpoint. The application accepts a user-controlled URL string through the issuerUrl parameter and performs an outbound HTTP request without validating if the destination IP belongs to a...

ActiveRecord::Tenanted::Storage::DiskService#path_for has a possible path traversal

Active Record Tenanted's override of Active Storage's DiskServicepathfor does not validate that the resolved filesystem path remains within the storage root directory. If a blob key containing path traversal sequences e.g. ../ is used, it could allow reading, writing, or deleting arbitrary files ...

Easy!Appointments Vulnerable to Appointments Takeover via Excessive Data Exposure

An Excessive Data Exposure vulnerability in the customers search endpoint allows an authenticated user to obtain appointment hashes belonging to other users. Using these hashes, an attacker can modify or delete appointments of other providers, resulting in an Appointments Takeover...

Easy!Appointments has server-side request forgery in CalDAV connection test that exposes the deployment's internal network

Caldav::connecttoserver at application/controllers/Caldav.php:60 hands the request's caldavurl to a Guzzle REPORT call without scheme or host validation. A logged-in backend user admin, provider, or secretary reaches loopback, RFC1918, and link-local hosts on the deployment's network. The Guzzle...

Easy!Appointments has unauthenticated customer PII disclosure on booking reschedule page

The booking reschedule view at /index.php/booking/reschedule/appointmenthash handled by Booking::index embeds the entire customer record as inline JavaScript const vars = ... "customerdata": ..., ... without authentication and without field whitelisting. Anyone in possession of the 12-character...

Easy!Appointments appointments/store and appointments/update allow cross-provider appointment injection — Authorization Bypass

Easy!Appointments correctly filters provider-scoped appointments in the appointments/search response, proving that provider isolation is an intended security boundary. However, the direct mutation endpoints appointments/store and appointments/update only check generic appointment privileges and...

Easy!Appointments disable_booking_message rendered as raw HTML on public booking page — Stored XSS

Easy!Appointments allows administrators to define a custom "booking disabled" message through the booking settings page. That value is stored in the disablebookingmessage setting via a rich-text editor and later passed directly to the public bookingmessage view without escaping or sanitization: p...

Easy!Appointments: Authorization bypass in Google OAuth provider binding lets any backend user rebind a peer provider's Google sync

Google::oauth at application/controllers/Google.php:278 stores its URL-supplied providerid in the session, and oauthcallback saves the issued Google OAuth token against that row without checking the caller owns the provider. Any logged-in backend user admin, provider, or secretary rebinds a peer...

LZ4 Java: Native XXHash implementations can crash the JVM when passed invalid byte array ranges

Insufficient validation of byte array arguments in JNI-based XXHash implementations in lz4-java 1.11.0 and earlier allows callers to crash the JVM by passing an invalid array reference or invalid range to native XXHash methods. This affects applications where an attacker can influence the byte...

swift-nio-http2: Missing CR/LF/NUL validation in header values

SwiftNIO HTTP/2 was missing validation on inbound HEADERS frames that let CR, LF, NUL, SP and other control characters reach an HTTP/1.1 backend through NIOHTTP2's HTTP/2-to-HTTP/1 codec, enabling HTTP request smuggling or response splitting...

Gitea: Webhooks created by a collaborator keep firing after their repo access is revoked → ongoing real-time exfiltration of private repo content

When a collaborator with admin permission on a private repo creates a webhook, that webhook keeps firing after the collaborator's access is revoked. Gitea's revocation cleanup DeleteCollaboration removes the collaboration record, recalculates accesses, drops watches, and unassigns issues — but it...

Gitea: Git LFS object reuse allows non-Code access to authorize private source objects

A user with Code write access to one repository may be able to associate an existing Git LFS object from a private source repository with their target repository, even when they do not have Code access to the source repository that currently owns the LFS object. The issue appears to be caused by...

Gitea: Private org member list leaked via /members API endpoint — incomplete fix for PR #38145

PR 38145 fixed ListPublicMembers and IsPublicMember but missed ListMembers. Any authenticated user can enumerate ALL members not just public ones of a private organization...

Gitea: Local File Inclusion via file:// URI in Migration Restore

Gitea's restore-repo command processes release.yml files from a user-supplied archive. The DownloadURL field in each release attachment is passed to uri.Open without scheme validation. Because uri.Open supports the file:// scheme via os.Open, an operator-level attacker can plant a crafted...

Gitea: Cross-repository IDOR in issue-dependency removal lets an attacker tamper with and comment on private repos they cannot access

This is a cross-repository IDOR / broken access control issue. An attacker can tamper with issue-tracking state dependency relationships and inject an attacker-authored comment into a private repository they cannot otherwise read or write to, crossing a trust boundary the "add" path explicitly...

Gitea: Public-only API token restriction is not enforced on team API routes

Gitea's /api/v1/teams/id API routes do not correctly enforce the public-only access token restriction. A public-only token is intended to limit API access to public repositories and public organizations. However, several team API routes continue to return private team repository metadata and...

Gitea: Fork-PR Actions task can read a third private repository via the collaborative-owner branch (missing fork-PR guard)

GetActionsUserRepoPermission models/perm/access/repopermission.go decides whether an Actions task token may access a target repo. Its cross-repo branches each enforce a fork-PR discriminator — except the collaborative-owner branch, which is missing the !task.IsForkPullRequest guard that its sibli...

AngleSharp HTML5 Spec Compliance: mXSS via annotation-xml HTML Integration Point Bypass

The HTML specification requires that a MathML element with encoding="text/html" or encoding="application/xhtml+xml" is treated as an HTML integration point. Content inside it must be parsed as HTML, not MathML. AngleSharp does not implement this correctly. As a result, the parser produces a DOM...

adawolfa/isdoc: Uncontrolled resource consumption (decompression bomb) when reading untrusted ISDOCX or PDF files

adawolfa/isdoc reads ISDOC invoices from ISDOCX ZIP archives and from PDF files with embedded ISDOC documents and supplements. Affected versions inflate ZIP entries and read embedded files without validating their uncompressed size, so a small crafted file can amplify into gigabytes: - ISDOCX...
