The attack vector is external: an attacker must supply crafted input, typically via URLs or form submissions, that is subsequently reflected in the page. No public exploit code is known, but the reflected nature of the XSS makes it simple for an attacker who can persuade a victim to click a malicious link."}}}}, "created": "2026-02-23T14:36:17.662985+00:00", "updated": "2026-04-16T16:45:25.959167+00:00", "vendors": ["spencer_haws", "spencer_haws$PRODUCT$link_whisper_free", "wordpress", "wordpress$PRODUCT$wordpress"]}
