ASN.1 Validator Desynchronization in node-forge
CVE-2025-12816 is a high-severity interpretation-conflict vulnerability in node-forge affecting versions 1.3.1 and earlier. The flaw is in the library’s ASN.1 validation/parsing behavior, including the asn1.validate logic used in cryptographic object handling. A remote, unauthenticated attacker can craft malformed ASN.1 structures that cause schema validation to become desynchronized from the semantics of the parsed data. As a result, data can appear to satisfy validation checks while being cryptographically incorrect or structurally inconsistent. Reported examples indicate this can affect downstream verification flows such as PKCS#12 MAC/signature-related processing, allowing malformed inputs to pass checks that applications expect node-forge to enforce.

A high-severity ASN.1 validator desynchronization vulnerability in node-forge 1.3.1 and below that can allow crafted ASN.1 structures to bypass downstream cryptographic verification and security decisions.
A critical vulnerability in the node-forge library allows attackers to bypass signature verification by manipulating ASN.1 structures. This could enable unauthorized actions or data tampering in applications relying on node-forge for cryptographic operations.
An interpretation-conflict vulnerability in node-forge versions 1.3.1 and earlier allows unauthenticated attackers to craft ASN.1 structures that desynchronize schema validations, potentially bypassing cryptographic verifications and security decisions. This can lead to authentication bypass, signed data tampering, and misuse of certificate-related functions in applications relying on node-forge for cryptographic integrity.
