CVE-2026-87869Network attack vector

Reflected XSS via unescaped pagination URL

Published Oct 10, 2026 · Updated Oct 10, 2026

Reflected XSS in Filter Everything — WordPress & WooCommerce Filters 1.9.6 and earlier lets remote attackers execute scripts via crafted links. The flrt_elementor_load_more_anchor() function decodes request query values, rebuilds them without URL encoding, and inserts the resulting URL into a data-next-page attribute without escaping. Exploitation requires a user to follow a crafted link to an affected Elementor pagination page; scripts execute in the site's browser context rather than on the server.
