A flaw in Node.js URL processing causes an assertion failure in native code when url.format is called with a malformed internationalized domain name IDN containing invalid characters, crashing the Node.js process...

BIT-NODE-2026-21715

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 --allow-fs-read can still use...

BIT-NODE-MIN-2026-21710

A flaw in Node.js HTTP request handling causes an uncaught TypeError when a request is received with a header named proto and the application accesses req.headersDistinct. When this occurs, dest"proto" resolves to Object.prototype rather than undefined, causing .push to be called on a non-array...

BIT-NODE-2026-21713

A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior...

An attacker with Global Builder privileges can craft a multipa...

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: 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...

nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions

A flaw was found in V8's string hashing mechanism within Node.js. A remote attacker can exploit this vulnerability by crafting requests containing integer-like strings.
