vm2 CLI provides no sandbox isolation - host-realm require() is reachable from sandboxed scripts

Summary The vm2 command-line tool installed by npm install -g vm2 and documented in the README's "CLI" section runs the supplied script under NodeVM with require:external:true and no root / context / builtin configured. With these defaults the resolver loads every relative or absolute require...

GHSA-2GC4-CQFQ-P2GV Socket.IO: Engine.IO Protocol Revision Mismatch DoS

Impact A denial-of-service vulnerability exists in Engine.IO / Socket.IO servers that allow transport upgrades. The Engine.IO protocol revision is negotiated during the initial handshake and stored on the session, but a newly-created transport, including a WebSocket upgrade transport, could...

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...

GHSA-WC9G-MQFW-JRWM multer vulnerable to Denial of Service via crafted multipart field names

Impact A vulnerability in multer allows a remote, unauthenticated attacker to crash the Node.js process with a single multipart/form-data request. Two specially crafted text field names cause an uncaught RangeError: Invalid array length inside multer's field parsing, which is not routed to the...

CVE-2026-85024

A flaw was found in undici. A remote, unauthenticated attacker can trigger a Denial of Service DoS by sending a specially crafted compressed WebSocket payload. When this payload exceeds the 128 MiB decompressed-payload limit and contains a malformed DEFLATE byte, it causes an unhandled error in t...

CVE-2026-19534

A flaw was found in undici. A remote attacker can exploit this vulnerability by responding with an unrequested WebSocket subprotocol during the opening handshake. This causes the undici WebSocket client to crash the entire Node.js process, leading to a denial of service DoS. Mitigation Mitigation...

CVE-2026-19534 undici vulnerable to Denial of Service via unrequested WebSocket subprotocol

undici's WebSocket client crashes the whole Node.js process during the opening handshake when a server responds with a subprotocol that the client never requested. A default WebSocket connection sends no subprotocol, but if the server's 101 response includes a Sec-WebSocket-Protocol header, undic...

undici: undici: Denial of Service via unhandled error in WebSocket permessage-deflate decompression

A flaw was found in undici. A remote, unauthenticated attacker can trigger a Denial of Service DoS by sending a specially crafted compressed WebSocket payload.
