{"id":"CVE-2026-17506","published":"2026-08-05T14:17:04.040","lastModified":"2026-08-05T17:16:44.440","description":"The Independent Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 404 not_found_url tracking parameter in versions up to, and including, 2.15.0. This is due to the get_cell_content() function applying urldecode() after esc_url() when rendering the URL column for 404 entries — a sequence that allows percent-encoded HTML to pass URL validation and then be reconstructed as raw markup, which wp_kses_post() does not strip because it retains img elements and data-* attributes, and because the public REST endpoint /iawp/search accepts unauthenticated requests as long as they carry a signature that is itself embedded in public page HTML. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/REST_API.php#L458","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/REST_API.php#L86","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Resource_Identifier.php#L126","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Tables/Table.php#L142","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Views/View.php#L206","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3627446%40independent-analytics%2Ftrunk%2FIAWP%2FUtils%2FRequest.php&old=3618630%40independent-analytics%2Ftrunk%2FIAWP%2FUtils%2FRequest.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/90ea5c51-e739-42c1-a276-851ad800ff00?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows unauthenticated attackers to inject arbitrary scripts via the 404 not_found_url parameter, leading to cross-site scripting (XSS).
