Technical details
The plugin contains a server-side template injection (SSTI) vulnerability in its popup text block functionality. A filter intended to strip template delimiters runs before a decoding step that reconstructs them, allowing authenticated administrator-level attackers to inject arbitrary template expressions that are evaluated by the template engine, leading to arbitrary code execution and information disclosure.
