CVE-2026-5737Network attack vector

Unauthenticated internal-host requests via unrestricted favicon fetches

Published May 28, 2026 · Updated May 28, 2026

Server-side request forgery in Independent Analytics 2.14.9 and earlier allows remote attackers to access internal services via tracking data. The public /wp-json/iawp/search route stores an attacker-controlled referrer_url, and the scheduled favicon downloader sends unrestricted cURL requests to the stored domain. A signature exposed in public JavaScript and a static per-site salt permit unauthenticated submission; the resulting requests can reach arbitrary hosts, including internal services.
