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 and parsing behavior, where crafted ASN.1 structures can cause schema validation to become desynchronized from the semantics later consumed by downstream cryptographic logic. This semantic divergence allows malformed or tampered ASN.1 data to satisfy validation checks even though the underlying cryptographic structure is not actually valid. Reported examples indicate the issue can affect verification flows involving recursively validated ASN.1 fields and PKCS-related structures, including proof-of-concept bypass of PKCS#12 MAC or signature-related verification logic. The result is that applications relying on node-forge to enforce ASN.1-derived trust boundaries may accept attacker-controlled data as valid.

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.
