Full Report
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. [...]
Analysis Summary
# Vulnerability: node-forge Signature Verification Bypass
## CVE Details
- CVE ID: CVE-2025-12816
- CVSS Score: High (Specific numerical score not provided in the summary, but described as having a "high severity rating")
- CWE: Not explicitly stated, related to ASN.1 validation/interpretation conflict.
## Affected Systems
- Products: `node-forge` JavaScript cryptography library
- Versions: 1.3.1 and earlier
- Configurations: Applications relying on `node-forge` for enforcing structure and integrity of ASN.1-derived cryptographic protocols.
## Vulnerability Description
The vulnerability is an interpretation-conflict flaw within `node-forge`'s ASN.1 validation mechanism. This allows unauthenticated attackers to craft specially malformed ASN.1 structures that pass initial validation checks, leading to a semantic divergence. This divergence can subsequently bypass downstream cryptographic verifications and security decisions.
## Exploitation
- Status: PoC available (A proof-of-concept was provided by the researcher)
- Complexity: Low (Implied, as application of forged payload tricks the mechanism)
- Attack Vector: Network (Likely, as the component handles remote/networked cryptographic data/signatures)
## Impact
The impact varies significantly based on the application context, but can include:
- Confidentiality: Potential loss (e.g., via authentication bypass)
- Integrity: Potential loss (e.g., signed data tampering)
- Availability: Minimal (Not the primary concern noted)
## Remediation
### Patches
- Update to `node-forge` version **1.3.2** or newer.
### Workarounds
- No explicit workarounds were detailed beyond immediate patching.
## Detection
- Detection specifics were not provided, but mitigation involves ensuring all applications using the library utilize validated/patched versions and scrutinizing any environment where cryptographic verification plays a central role in trust decisions.
