CVE-2026-83543 Details
Description
The Greenshift WordPress plugin before 13.2.0 does not validate a user-supplied URL before fetching it server-side, allowing users with contributor-level access and above to make the server issue requests to arbitrary hosts and read the response.
A server-side request forgery (SSRF) vulnerability has been identified in the Greenshift WordPress plugin, affecting versions prior to 13.2.0. The vulnerability arises because the plugin does not properly validate user-supplied URLs before fetching them server-side. This flaw allows users with contributor-level access and above to make the server send requests to arbitrary hosts and read the responses. The issue is particularly concerning as it could potentially be exploited to access internal resources, although testing indicated that WordPress core's request wrapper blocks such attempts.
Users are advised to update the Greenshift WordPress plugin to version 13.2.0 or later.
