CVE-2026-83543
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.
Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
