A vulnerability in the ‘node-forge’ package, a popular JavaScript cryptography library, could be exploited to bypass signature verifications by crafting data that appears valid.
The flaw is tracked as CVE-2025–12816 and received a high severity rating. It arises from the library’s ASN.1 validation mechanism, which allows malformed data to pass checks even when it is cryptographically invalid.
“An interpretation-conflict vulnerability in node-forge versions 1.3.1 and earlier enables unauthenticated attackers to craft ASN.1 structures to desynchronize schema validations, yielding a semantic divergence that may bypass downstream cryptographic verifications and security decisions,” reads the flaw’s description in the National Vulnerabilities Database (NVD).
