Public CAS validation/proxy endpoints pass attacker-controlled `ticket` / `pgt` query parameters into this store.\n\nIn deployments using `FileSystemTicketStore`, a remote attacker can use path traversal sequences such as `../target.serialized` to make the CAS server read and unserialize files outside the ticket directory. In the CAS 1.0 validation flow, the same attacker-selected path is also passed to `deleteTicket()` immediately after `getTicket()` returns, which can delete the target file when it is readable by the PHP process, deletable under the PHP process filesystem permissions, and unserializes to a value compatible with the `?array` return type.\n\n### Preconditions\n\nThe demonstrated issue requires:\n\n- the `casserver` module to be enabled;\n- the file-based ticket store to be configured (`FileSystemTicketStore`);\n- public CAS validation/proxy endpoints to be reachable;\n- the PHP process to have filesystem permissions for the target path.\n- for the demonstrated CAS 1.0 deletion","public_affected_ranges":["ECOSYSTEM: introduced 0; fixed 7.0.3"]}],"null_published_at":"2026-10-31T22:00:33.874Z","source_updated_at":"2026-09-10T03:50:55.330Z","source_disclosed_at":"2026-05-15T18:07:51.000Z","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":"2026-10-31T21:42:30.970Z"}],"next_cursor":null,"snapshot_revision":"42594"}
