CVE-2026-42867

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow is vulnerable to Path Traversal in the Knowledge Bases API POST /api/v1/knowledgebases. This occurs because user-supplied knowledge base names are used directly to create file paths without...

CVE-2026-33760

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow's /api/v1/monitor router exposes 7 endpoints that perform read, write, and delete operations on user-owned resources — messages, sessions, build artifacts, and LLM transaction logs — without...

GHSA-C39W-43GM-34H5 Gogs has Path Traversal in organization name that results in RCE through Git hooks

Summary Organization names containing path traversal sequences ../ are accepted by Gogs, and repositories under them are written to paths following these path traversals. This allows storing/retrieving data for repositories at arbitrary locations on the filesystem. By creating nested structure of...

GHSA-89MR-XQFV-758M Gogs: UploadRepoFiles writes outside repo working tree via committed parent sym

Summary Repository.UploadRepoFiles checks for symlinks only on the leaf of the upload target osx.IsSymlinktargetPath. The siblings UpdateRepoFile, DeleteRepoFile, and GetDiffPreview use hasSymlinkInPath, which lstats every component — UploadRepoFiles is the lone outlier. An attacker with repo-wri...

Gogs allows users to write to readonly repositories using receive-pack + service=git-upload-pack confusion

Summary Git smart HTTP authorizes POST …/git-receive-pack using the client-supplied service query string so ?service=git-upload-pack is evaluated as read access while routing still runs git receive-pack, allowing push where only read should be allowed. Details Gogs' Git Smart HTTP handler for...

Gogs's write-level collaborators can mutate admin-only repository settings via API

Summary Three API endpoints — PATCH /api/v1/repos/:owner/:repo/issue-tracker, PATCH /api/v1/repos/:owner/:repo/wiki, and POST /api/v1/repos/:owner/:repo/mirror-sync — are gated by reqRepoWriter rather than reqRepoAdmin. The equivalent operations in the web UI sit behind reqRepoAdmin, which requir...

CVE-2026-33760

Langflow (pre-1.9.0) exposes an IDOR/BOLA vulnerability in the /api/v1/monitor router. Seven endpoints (including builds, messages, and transactions) allow read, write, and delete actions on user-owned resources without verifying ownership, enabling an attacker to access or modify another user’s ...

CVE-2026-33760 Langflow: IDOR/BOLA in Monitor API — Missing Ownership Enforcement on 7 Endpoints

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow's /api/v1/monitor router exposes 7 endpoints that perform read, write, and delete operations on user-owned resources — messages, sessions, build artifacts, and LLM transaction logs — without...

CVE-2026-42867 Langflow: Path Traversal in Knowledge Bases API via Creation Endpoint

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow is vulnerable to Path Traversal in the Knowledge Bases API POST /api/v1/knowledgebases. This occurs because user-supplied knowledge base names are used directly to create file paths without...

CVE-2026-50574

yt-dlp is a command-line audio/video downloader. Prior to 2026.06.09, if aria2c is used as an external downloader for a fragmented manifest format such as an HLS/DASH stream, yt-dlp passes insufficiently sanitized input to aria2c that allows an attacker to perform an arbitrary file write. On...

CVE-2026-50574

CVE-2026-50574 affects yt-dlp, where using aria2c as an external downloader for fragmented manifests (HLS/DASH) allows an attacker to write arbitrary files by passing insufficiently sanitized input to aria2c. On Windows, this can cause immediate arbitrary code execution; on non-Windows, execution...

CVE-2026-50574 yt-dlp: Arbitrary code execution via manifest downloads with aria2c

yt-dlp is a command-line audio/video downloader. Prior to 2026.06.09, if aria2c is used as an external downloader for a fragmented manifest format such as an HLS/DASH stream, yt-dlp passes insufficiently sanitized input to aria2c that allows an attacker to perform an arbitrary file write. On...

CVE-2026-56115

Bootimus through 0.1.70 contains a broken access control vulnerability that allows authenticated low-privileged users to perform administrative actions by exploiting missing role enforcement in the JWTMiddleware function in internal/auth/auth.go, which validates JWT tokens and account status but...

CVE-2026-56115 Bootimus 0.1.70 Broken Access Control via JWTMiddleware Authorization Bypass

Bootimus through 0.1.70 contains a broken access control vulnerability that allows authenticated low-privileged users to perform administrative actions by exploiting missing role enforcement in the JWTMiddleware function in internal/auth/auth.go, which validates JWT tokens and account status but...

CVE-2026-50023

yt-dlp is a command-line audio/video downloader. Prior to 2026.06.09, a vulnerability exists in yt-dlp that allows a remote attacker to write arbitrary OS-shortcut files such as .desktop, .url, .webloc to the user's filesystem, bypassing the remediation for CVE-2024-38519. The allowlist explicitl...

CVE-2026-56114 dhcpcd Stack Out-of-Bounds Write in dhcp6_makemessage()

dhcpcd through 10.3.2, fixed in commit 2f00c7b, contains a one-byte stack out-of-bounds write vulnerability in dhcp6makemessage in src/dhcp6.c that allows unauthenticated same-link attackers to write beyond a fixed local buffer by serializing an oversized RFC6603 OPTIONPDEXCLUDE option body...

CVE-2026-11940

tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower...

CVE-2026-12958 Arbitrary file write in Language Servers for AWS

Missing symlink validation in Language Servers for AWS may allow an arbitrary file write outside of the workspace trust boundary. This may occur when a local user opens a workspace with a maliciously crafted symlink that resolves to a file path outside the workspace trust boundary. To remediate...
