What is CVE-2026-17506?

CVE-2026-17506 is a high-severity cross-site scripting vulnerability in bensibley Independent Analytics – WordPress Analytics Plugin, published on 5 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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.

Weakness: CWE-79
