CRITICAL 9.1EPSS 0.33%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Dancer2::Plugin::Auth::OAuth versions before 0.22 for Perl default to a predictable nonce. The default nonce was generated using an MD5 hash of the epoch time, which is predictable.
