CVE-2023-28619Network attack vector

Subscriber-level plugin activation via missing capability check

Published Dec 24, 2025 · Updated Dec 24, 2025

Missing authorization in Resoto 1.0.8 and earlier allows remote authenticated users to activate arbitrary installed plugins via AJAX. The theme's activate_plugin function processes a requested plugin through an AJAX endpoint without checking the caller's activation capability, then suppresses the resulting notice. Subscriber-level access is sufficient to enable any plugin already present on the site, changing site behavior without granting plugin installation rights.
