AI-suggested
If you cannot patch yet, users should consider implementing custom nonce generation using a cryptographically secure random number generator or upgrading to version 0.22 or later once available.
Description
Dancer2::Plugin::Auth::OAuth versions before 0.22 for Perl use a predictable nonce generated by hashing the epoch time with MD5, which is a cryptographically weak pseudo-random number generator. This vulnerability (CVE-2026-11832) can lead to compromised confidentiality and integrity of authentication tokens. The CVSS score is 9.1, indicating a critical severity level.
