# CVE-2026-118422: Stape Conversion Tracking 2.3.0 - 2.3.10 - Unauthenticated SSRF and Same-Origin XSS via Proxy Sub-Path

Status: published. Published: 2026-11-04. Updated: 2026-11-04.

The Stape Conversion Tracking WordPress plugin before 2.3.11 does not validate the sub-path appended to its same-origin proxy's upstream endpoint, allowing unauthenticated visitors to redirect the server-side request to an arbitrary host and have the response body and its content type returned from the site's own origin with security response headers stripped, leading to Server-Side Request Forgery, including loopback and internal hosts, and Cross-Site Scripting.
