Machine-written summary

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

Ory fosite versions before 0.34.0 have a flaw in the token revocation handler, which ignores errors returned by storage. When storage fails, the handler can still return a success status even though the token remains valid. Exploitation depends on an attacker being able to trigger storage errors. Upgrade to fosite 0.34.0 or later.

Written 6 Nov 2026.
