Popular Forge Library Receives Fix for Signature Verification Bypass

Popular Forge Library Receives Fix for Signature Verification Bypass Flaw Source: www.bleepingcomputer.com/news/secu… A high-severity vulnerability in the node-forge package, a widely used JavaScript cryptography library, has been patched after researchers discovered a method to bypass digital signature verification. Tracked as CVE-2025-12816, the flaw stems from weaknesses in the library’s ASN.1 validation logic. The issue allowed specially crafted, malformed data to pass signature checks despite being cryptographically invalid. According to an advisory from Carnegie Mellon CERT-CC, the risk varies by implementation but may include: Authentication bypass Tampering with signed data Misuse or manipulation of certificate-related functionality CERT-CC noted that environments relying heavily on cryptographic verification could face particularly serious consequences. The potential impact is amplified by the library’s widespread adoption, with nearly 26 million weekly downloads on the NPM registry.
