Summary
The Stape Conversion Tracking WordPress plugin from 2.3.0 before 2.3.11 does not validate the sub-path appended to its same-origin proxy's upstream endpoint (CWE-918). An unauthenticated visitor can redirect server-side requests to arbitrary hosts, including loopback and internal hosts, and receive the response body and content type from the site's own origin with security response headers stripped, which enables cross-site scripting. The references link to an exploit.

Description from the CNA
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.
