To Do List Member · Vulnerability

CVSS 3.1 8.8 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-86801

Published

The To Do List Member WordPress plugin from 1.4 through 1.6 ships a file upload endpoint that does not load WordPress and therefore applies no authentication, capability or nonce check of any kind, and validates only the name of an uploaded file rather than its content, allowing unauthenticated users to store active content served from the site's own origin, and to list and delete the files already staged there.
