CVE-2025-49374Network attack vector

Unauthenticated server-side requests via undisclosed endpoint

Published Oct 22, 2025 · Updated Oct 22, 2025

Server-side request forgery in Captcha.eu 1.0.61 and earlier allows remote attackers to send requests from a WordPress server. Patchstack and the CNA have not published the vulnerable endpoint or the operation that accepts and fetches an attacker-controlled URL. No authentication or user interaction is required; the requests can query internal services, while CISA's assessment limits the confirmed impact to information disclosure.
