{"id":"CVE-2026-100106","state":"PUBLISHED","title":"FiboSearch <= 1.34.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'purchased_plan' Parameter","description":"The FiboSearch – Ajax Search for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'purchased_plan' parameter in all versions up to, and including, 1.34.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the site owner has previously completed the standard Freemius opt-in flow; once that condition is met, any Subscriber can reach the vulnerable handler simply by loading /wp-admin/profile.php with the requisite query parameters.","publishedAt":"2026-10-16T07:44:02.898Z","updatedAt":"2026-10-16T14:15:55.302Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["damian-gora FiboSearch – Ajax Search for WooCommerce"],"affected":[{"vendor":"damian-gora","product":"FiboSearch – Ajax Search for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.34.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7db3475a-3a70-4776-8ea3-337192f88973?source=cve","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/vendor/freemius/wordpress-sdk/includes/class-freemius.php#L4548","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/vendor/freemius/wordpress-sdk/includes/fs-core-functions.php#L223","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/vendor/freemius/wordpress-sdk/includes/managers/class-fs-admin-notice-manager.php#L421","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/vendor/freemius/wordpress-sdk/templates/admin-notice.php#L110","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/vendor/freemius/wordpress-sdk/includes/fs-html-escaping-functions.php#L123","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/assets/js/admin.js#L555","https://plugins.trac.wordpress.org/browser/ajax-search-for-woocommerce/tags/1.34.2/assets/js/tooltip.min.js#L4","https://plugins.trac.wordpress.org/changeset?reponame=&new=3734423%40ajax-search-for-woocommerce%2Ftags%2F1.34.3&old=3684506%40ajax-search-for-woocommerce%2Ftags%2F1.34.2"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/100xxx/CVE-2026-100106.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-100106","state":"PUBLISHED","datePublished":"2026-10-16T07:44:02.898Z","dateUpdated":"2026-10-16T14:15:55.302Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-25T11:15:22.410Z"},"containers":{"cna":{"title":"FiboSearch <= 1.34.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'purchased_plan' Parameter","descriptions":[{"lang":"en","value":"The FiboSearch – Ajax Search for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'purchased_plan' parameter in all versions up to, and including, 1.34.2 due to insufficient input sanitization and output escaping.
