The vulnerability is not listed in CISA\u2019s KEV catalog, further indicating limited evidence of active attacks. Attackers can exploit the flaw by creating or editing content within the Composer interface, injecting JavaScript that is then rendered to all page visitors. Because the payload is stored, the attack is persistent and can affect authenticated and unauthenticated users alike."}}}}, "created": "2026-04-08T19:27:43.325636+00:00", "updated": "2026-04-08T19:40:28.110861+00:00", "vendors": ["tagdiv", "tagdiv$PRODUCT$tagdiv_composer", "wordpress", "wordpress$PRODUCT$wordpress"]}
