CVE-2026-4600
jsrsasign: jsrsasign: Cryptographic signature forgery via malicious DSA domain parameters
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon GHSA (élevée), Red Hat (élevée).
Description
Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic (and the related DSA/X509 verification flow in src/dsa-2.0.js). An attacker can forge DSA signatures or X.509 certificates that X509.verifySignature() accepts by supplying malicious domain parameters such as g=1, y=1, and a fixed r=1, which make the verification equation true for any hash.
