What is CVE-2026-9109?

The GPTranslate plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability due to insufficient input sanitization and output escaping when handling requests to the REST API Translation Storage. Attackers can exploit this weakness to inject arbitrary web scripts, which will execute when a user accesses an impacted page. Additionally, the API key can be easily accessed from the HTML source, enabling unauthenticated users to submit malicious translation requests, further compromising the security of the site.
