Technical details
The plugin is vulnerable to Stored Cross-Site Scripting (XSS) in the translation editor's strings dropdown, where approved comment bodies are rendered without adequate input sanitization or output escaping. An authenticated attacker with subscriber-level permissions or above can inject arbitrary JavaScript into the translation system, and this malicious payload persists in the database. When any user accesses a page containing the injected translation string, the script executes in their browser context, enabling session hijacking, data theft, or further malware distribution. The vulnerability affects all versions up to and including 3.2.6; patches beyond this version should be available.
