CVE-2023-27456Network attack vector

Subscriber-level plugin activation via unchecked handler

Published Dec 13, 2024 · Updated Apr 28, 2026

Missing authorization in HashThemes Total 2.1.19 and earlier allows remote authenticated users to activate arbitrary installed plugins. The activate_plugin function accepts a requested plugin without adequate capability or nonce checks and invokes its activation. Subscriber access is sufficient; the action changes site plugin state but does not by itself install new code or grant administrator access.
