CVE-2026-4599 (GCVE-0-2026-4599)

Vulnerability from cvelistv5 – Published: 2026-03-23 05:00 – Updated: 2026-07-01 12:04
VLAI
Summary
Versions of the package jsrsasign from 7.0.0 and before 11.1.1 are vulnerable to Incomplete Comparison with Missing Factors via the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions in src/crypto-1.1.js; an attacker can recover the private key by exploiting the incorrect compareTo checks that accept out-of-range candidates and thus bias DSA nonces during signature generation.
Severity
9.1 (Critical)
