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 was found in Node.js. The HTTPS Agent, responsible for managing secure connections, can incorrectly reuse client identities across different requests. This occurs due to a technical issue with PFX object-array key collisions during connection reuse. As a result, a client's identity, established through mutual TLS (mTLS) authentication, could be mistakenly applied to another request, potentially leading to unauthorized access or identity spoofing.
