This is due to insufficient input sanitization and output escaping in the flrt_elementor_load_more_anchor() function. The function reads query parameters from $_SERVER['REQUEST_URI'] via getFormActionOrFullPageUrl(true), which URL-decodes them through parse_str() and re-assembles them using build_query() — a WordPress core function that does NOT re-encode values ($urlencode=false). The resulting URL, containing unescaped special characters, is injected into a data-next-page HTML attribute via preg_replace() without esc_attr() or esc_url(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.","state":0,"publishedAt":"2026-10-10T04:26:45.199+00:00","modifiedAt":"2026-10-11T12:23:58.93+00:00","affected":[{"ecosystem":"Vendor product","name":"Filter Everything\u00A0— WordPress & WooCommerce Filters","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"stepasyuk\",\n                    \"product\": \"Filter Everything\u00A0— WordPress & WooCommerce Filters\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.9.6\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7f0f453c-ca01-4ccc-b8c0-4468db40386a?source=cve","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/wpc-third-party.php#L793","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/UrlManager.php#L197","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/wpc-helpers.php#L207","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/wpc-third-party.php#L793","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/UrlManager.php#L197","https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/wpc-helpers.php#L207","https://plugins.trac.wordpress.org/changeset?reponame=&old=3707235%40filter-everything&new=3707235%40filter-everything"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-87869","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-87869","identifiers":["CVE-2026-87869"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
