What is CVE-2026-5737?
CVE-2026-5737 is a medium-severity server-side request forgery vulnerability in bensibley Independent Analytics – WordPress Analytics Plugin, published on 28 May 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 Server-Side Request Forgery in all versions up to, and including, 2.14.9. This is due to a public tracking route at /wp-json/iawp/search that accepts attacker-controlled referrer_url values when the signature matches, combined with a scheduled favicon fetcher that performs unrestricted cURL requests to stored domains. The signature validation is insufficient because the signature is embedded in publicly-accessible JavaScript and the salt is static per site, allowing attackers to extract valid signatures. The favicon downloader uses raw cURL functions without any SSRF protection mechanisms (no localhost blocking, no private network filtering, and does not use WordPress's wp_safe_remote_* functions). This makes it possible for unauthenticated attackers to inject malicious referrer domains into the database and trigger server-side requests to arbitrary hosts including internal services.
