A sanitizer bypass allows injected script to execute same-origin as the editor. When a victim opens the preview, the script can call authenticated APIs using the victim's session. An account with global:member privileges can exploit the issue.","public_affected_ranges":["< 1.123.64"]}],"null_published_at":"2026-11-04T10:04:27.903Z","source_updated_at":"2026-07-22T17:55:01.000Z","source_disclosed_at":"2026-07-22T12:32:18.000Z","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":"2026-11-03T22:34:39.734Z"}],"next_cursor":null,"snapshot_revision":"42594"}
