Score 9.1 from GitHub Security Advisory (severity: CRITICAL) published 2026-06-16. CISA-ADP (Vulnrichment) CVSS v3.1 baseline 9.1; sources differ by 0.0.
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
Crypt::DSA versions before 1.21 for Perl reused the nonce across signatures, leading to private-key recovery.
Crypt::DSA::sign caches the per-signature nonce material in the Key object without ever clearing it.
The first sign() on a Key object picks a nonce, and every later sign() on that same object reuses it, producing an identical "r".
Keys used to sign more than once with an affected version should be considered compromised.
