CVE-2026-27181Public exploitNetwork attack vector

Unauthenticated module deletion via unchecked market mode

Published Feb 18, 2026 · Updated Feb 18, 2026

Missing authorization in the MajorDoMo market module allows remote attackers to delete arbitrary installed modules via crafted GET requests. The admin() method copies request-controlled mode into its internal mode before any administrative action check, exposing uninstallPlugin(). Unauthenticated access to /objects/?module=market is sufficient to remove module database records, directories, templates, and cycle scripts.
