9.1 · CRITICALOverview
CVE-2026-12205 is a critical-severity vulnerability. It was published on June 15, 2026 and has a CVSS 3.1 base score of 9.1 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
