Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The doorkeeper gem, versions 5.0.0 before 5.0.3, 5.1.0 before 5.1.1, 5.2.0 before 5.2.5, and 5.3.0 before 5.3.2, exposes all Doorkeeper::Application attribute values, including secrets, through the authorized applications controller when that controller is enabled. An attacker with access to that endpoint can read application secrets. Upgrade to 5.0.3, 5.1.1, 5.2.5, or 5.3.2 depending on your release line; enabling application secret hashing (available since 5.1) also limits the impact.
