{"cve":"CVE-2026-17506","nvd":{"published":"2026-08-05T14:17:04.040","modified":"2026-08-12T21:00:37.147","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/REST_API.php#L458","https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/REST_API.php#L86","https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Resource_Identifier.php#L126","https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Tables/Table.php#L142","https://plugins.trac.wordpress.org/browser/independent-analytics/tags/2.15.0/IAWP/Views/View.php#L206"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-17506","score":0.00399,"percentile":0.34159,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
