K000162902: Node.js vulnerability CVE-2026-21715

Security Advisory Description A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync.native without the required read permission checks, while all comparable filesystem functions correctly enforce them. As a result, code running under --permission with restricted...

CVE-2026-73643: Inefficient Algorithmic Complexity

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 until 5.2.2, parsing a small YAML document can take exponential time when an application calls load or loadAll on untrusted input. In src/parser/parser.ts, readFlowCollection uses restoreState and calls parseNode a second time when a...

PT-2026-71408

Name of the Vulnerable Software and Affected Versions @fastify/busboy versions 3.1.0 through 3.2.0 Description A remote unauthenticated attacker can cause a Denial of Service by stalling the Node.js event loop. This occurs when a multipart request is sent with a boundary crafted to exactly 252...

CVE-2026-19484: Loop with Unreachable Exit Condition

@fastify/busboy is a multipart form-data parser. In versions 3.1.0 through 3.2.0, a remote unauthenticated attacker can stall the Node.js event loop by sending a multipart request whose boundary is crafted to a specific length. The vendored streaming search stores its skip table in a fixed 256...

CVE-2026-73561: Uncontrolled Resource Consumption

Hub is a Node.js WebSocket server and client with added features. Prior to 0.2.16, every incoming unauthenticated WebSocket connection triggers loadDefaultConnectionEventListeners to call requestClientId, which calls rpc.send for the get-client-id action and pushes a request into RPC.requests. Th...

CVE-2026-73650: Improper Neutralization of Input During Web Page Generation

SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.3, 3.3.4, and 4.0.2, the removeScripts plugin, named removeScriptElement in versions 1 through 3, can leave executable content in optimized SVGs because...

undici: Undici: Response truncation and connection termination

A flaw was found in undici, a Node.js HTTP/1.1 client. When the dump interceptor processes oversized chunked responses that do not declare a Content-Length, it prematurely signals completion. This causes the application to receive an incomplete or empty response body, while the network connection...

undici: undici: Denial of Service via WebSocketStream unclean close

A flaw was found in undici's experimental WebSocketStream client. A remote attacker, operating as an untrusted server, can trigger a Denial of Service DoS by closing the TCP connection without a proper WebSocket close handshake. This action causes an unhandled error in the client, leading to the...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...

CVE-2026-73299

Prompty is a markdown file format .prompty for LLM prompts. Prior to 0.1.5 and 2.0.0-beta.5, the TypeScript Nunjucks renderer evaluated untrusted .prompty template bodies with unrestricted JavaScript member access. An attacker-controlled template could traverse constructor and prototype propertie...

CVE-2026-73291 Seerr: Path traversal to RCE via /avatarproxy image cache filename from upstream ETag

Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby. Prior to version 3.4.0, Seerr's ImageProxy in server/lib/imageproxy.ts uses the upstream ETag and Content-Type response headers to build a cache filename for the unauthenticated GET...

CVE-2026-73291

Seerr (open-source media manager for Jellyfin/Plex/Emby) prior to v3.4.0 contains a flaw in ImageProxy: the code uses upstream ETag and Content-Type headers to build the cache filename for the unauthenticated GET /avatarproxy/:jellyfinUserId route. This allows a malicious or compromised Jellyfin/...
