Technical details

The Popup Maker plugin for WordPress (versions up to 1.22.0) contains a missing authorization check (CWE-862) in its REST API implementation. Specifically, the legacy v1/connect/info endpoint can be manipulated to issue a bearer token that satisfies the validation requirements of the install endpoint. An authenticated attacker with editor-level permissions or higher can use this token to install and activate an arbitrary plugin from a remote URL. This leads to Remote Code Execution (RCE) on the underlying server. Exploitation is contingent upon a valid Popup Maker Pro license being active on the site while the Pro version itself is not yet installed.
