That resolver only lexically collapses .. segments (no realpath()/containment check) and, for the default file:// scheme, resolves straight to file_exists() with no re-validation against the registered stream root. A relative-path traversal string therefore resolves to an arbitrary absolute path on disk. If that path is a valid image, its pixel content is composited into the carrier image and the result is cached and served from a public, unauthenticated URL — i.e. any file outside Grav's media sandbox that happens to be a decodable image becomes visible to anonymous visitors, not just to the attack","public_affected_ranges":["ECOSYSTEM: introduced 2.0.10; fixed 2.0.11"]}],"null_published_at":"2026-10-31T22:13:14.317Z","source_updated_at":"2026-09-17T17:30:05.672Z","source_disclosed_at":"2026-09-17T17:16:56.000Z","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":"2026-10-31T21:42:41.381Z"}],"next_cursor":null,"snapshot_revision":"42594"}
