CVE-2026-4600

CVE-2026-4600 affects the JavaScript library jsrsasign prior to 11.1.1. The vulnerability stems from improper verification of cryptographic signatures due to DSA domain-parameter validation in KJUR.crypto.DSA.setPublic (and related DSA/X509 verification in src/dsa-2.0.js). An attacker can forge D...
