CVE-2026-4601

A flaw was found in jsrsasign. An attacker can exploit a missing cryptographic step in the Digital Signature Algorithm DSA signing process, specifically within the KJUR.crypto.DSA.signWithMessageHash function. By manipulating the signature generation to force specific values, the library emits an...

CVE-2026-4601

Versions of the package jsrsasign before 11.1.1 are vulnerable to Missing Cryptographic Step via the KJUR.crypto.DSA.signWithMessageHash process in the DSA signing implementation. An attacker can recover the private key by forcing r or s to be zero, so the library emits an invalid signature witho...
