Specifically, the authentication middleware exempts any URL path ending with 'health' or 'ready' from authentication checks. This allows an attacker to create resources with names ending in 'health' or 'ready' and access them without authentication. Affected endpoints include those for variables, flows, work pools, work queues, and deployments. This vulnerability can lead to unauthorized access to sensitive information, such as API keys and database credentials, stored in Prefect Variables.","public_affected_ranges":["< 3.6.22.dev7"]}],"null_published_at":"2026-11-05T19:10:21.456Z","source_updated_at":"2026-07-09T20:53:14.000Z","source_disclosed_at":"2026-06-02T09:36:15.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-04T23:34:40.400Z"}],"next_cursor":null,"snapshot_revision":"42594"}
