CVE-2026-33895

A flaw was found in Forge (also called node-forge), a JavaScript library used for Transport Layer Security (TLS). The library's Ed25519 signature verification process does not correctly validate cryptographic signatures, allowing forged non-canonical signatures to be accepted. A remote attacker could exploit this signature malleability to bypass authentication and authorization logic. This vulnerability can also circumvent security checks in applications that rely on the uniqueness of cryptographic signatures for functions such as deduplication or preventing replay attacks.
