{"schema":"threatline.record/2","record":{"id":"CVE-2026-87869","aliases":[],"summary":"Filter Everything — WordPress & WooCommerce Filters <= 1.9.6 - Reflected Cross-Site Scripting via Elementor Posts Widget Pagination URL","details":"The Filter Everything — WordPress & WooCommerce Filters plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 1.9.6. 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.","categories":["Applications & CMS"],"product":"Filter Everything — WordPress & WooCommerce Filters","vendor":"stepasyuk","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-87869","source_modified_at":"2026-10-11T12:23:58.930Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Filter Everything — WordPress & WooCommerce Filters","vendor":"stepasyuk","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.9.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0022,"percentile":0.11884,"score_date":"2026-10-23"},"published_at":"2026-10-10T04:26:45.199Z","modified_at":"2026-10-11T12:23:58.930Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-87869","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T12:23:58.930Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-87869","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7f0f453c-ca01-4ccc-b8c0-4468db40386a?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/wpc-third-party.php#L793"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/UrlManager.php#L197"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.6/src/wpc-helpers.php#L207"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/wpc-third-party.php#L793"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/UrlManager.php#L197"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/filter-everything/tags/1.9.2.1/src/wpc-helpers.php#L207"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3707235%40filter-everything&new=3707235%40filter-everything"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-11T12:17:46.057058Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-11T12:23:58.930Z","content_hash":"a0ce77a0d3b49f2e786a04a249ddd3d9022df42dea8febad5433cd69f1e639c5"}}
