nodejs: Nodejs denial of service

A denial of service flaw has been discovered in NodeJS. A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of...

nodejs: Nodejs file permissions bypass

A flaw in Node.js’s Permissions model allows attackers to bypass --allow-fs-read and --allow-fs-write restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files...

nodejs: Nodejs denial of service

A stack overflow flaw has been discovered in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when asynchooks.createHook is enabled. Instead of reaching process.on'uncaughtException', the process terminates, making the crash unrecoverable. Applications tha...

nodejs: Node.js: Permission bypass allows unauthorized modification of file permissions and ownership via incomplete security fix.

A flaw was found in Node.js. An incomplete security fix allows code operating under restricted file system write permissions to bypass these limitations. This vulnerability enables the modification of file permissions and ownership on already-open files, even when explicit write access is denied...

nodejs: Nodejs network segmentation bypass

A flaw in Node.js's permission model allows Unix Domain Socket UDS connections to bypass network restrictions when --permission is enabled. Even without --allow-net, attacker-controlled inputs such as URLs or socketPath options can connect to arbitrary local sockets via net, tls, or undici/fetch...
