CVE-2026-86591 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The Botiga Pro WordPress plugin before 1.6.5 does not perform any authorisation checks on one of its REST routes, allowing unauthenticated users to update arbitrary WordPress options with arbitrary values, which could lead to privilege escalation and a full site takeover. The same route also allows unauthenticated users to store arbitrary web scripts which are then executed on every page of the site's front end, as well as to move arbitrary posts to the trash.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
