A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries.

Under --permission, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist.

This vulnerability affects Node.js main, 22.x, 24.x, and 26.x.

A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS (mTLS) client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js 26.x, 24.x, and 22.x.

A flaw in Node.js Permission Model enforcement allows traceevents.createTracing().enable() Writes Trace Logs Outside --allow-fs-write. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects Node.js 22.x, 24.x, and 26.x.

A flaw in Node.js Permission Model enforcement allows Bypass via process.report.writeReport() Path Misvalidation. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
