CVE-2025-45765 (opens in a new tab)How to fix?
There is no fixed version for Debian:12 ruby-jwt.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby-jwt package and not the ruby-jwt package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
ruby-jwt v3.0.0.beta1 was discovered to contain weak encryption. NOTE: the Supplier's perspective is "keysize is not something that is enforced by this library. Currently more recent versions of OpenSSL are enforcing some key sizes and those restrictions apply to the users of this gem also."
