This results in tokens being created with only the default policy, default TTL, and no entity information, which are hidden by the returned error message. No access to these tokens by the caller occurs and the authentication token is not ever made accessible outside of `sys/raw`. At most this could cause storage usage.\n\n### Patches\n\nThis is fixed in OpenBao v2.5.4. \n\n### Workarounds\n\nUsers may set a rate limit quota to limit the creation of these paths. As the path is unauthenticated, it isn't possible to deny access to it.\n\n### Reporter\n\nThis was discovered by an anonymous reporter.","public_affected_ranges":["<= 2.5.3"]}],"null_published_at":"2026-11-07T07:07:39.844Z","source_updated_at":"2026-05-28T18:55:24.000Z","source_disclosed_at":"2026-05-28T18:55:23.000Z","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":"2026-11-07T00:53:22.747Z"}],"next_cursor":null,"snapshot_revision":"42594"}
