This link is maintained to preserve external references.\n\n### Original Description\nGrav CMS before 2.0.16 contains an origin validation bypass in the Uri::referrer() and Pages::referrerRoute() methods, which validate the Referer header using an unanchored string prefix match (str_starts_with($referrer, $base)) with no trailing delimiter. An attacker who controls a domain that begins with the victim site's origin (e.g. https://example.com.attacker.tld) can send a request with such a Referer to be treated as same-origin, bypassing the Referer-based origin check.","public_affected_ranges":["ECOSYSTEM: introduced 0"]}],"null_published_at":"2026-10-31T22:13:14.310Z","source_updated_at":"2026-09-17T20:45:06.681Z","source_disclosed_at":"2026-08-25T03:32:09.000Z","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":"2026-10-31T21:42:31.003Z"}],"next_cursor":null,"snapshot_revision":"42594"}
