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. node-forge: Forge: Authentication bypass via forged Ed25519 cryptographic signatures The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
