KEV: No
Impact: Stored Cross‑Site Scripting via unauthenticated REST API
Action: Immediate Patch
AI Analysis

Impact

The GPTranslate WordPress plugin, prior to version 2.34.14, fails to enforce access control on its REST API endpoints that allow translation storage. Attackers can submit arbitrary translation data that is later reflected on translated pages without proper escaping, granting them stored Cross‑Site Scripting capabilities. Successful exploitation can lead to theft of user credentials, session hijacking, or defacement of sites rendered with those translations.

Affected Systems

The vulnerability affects all installations of the GPTranslate WordPress plugin older than 2.34.14. No specific WordPress core versions are mentioned, so any site running the plugin before the patched release is at risk.

Risk and Exploitability

The CVSS score of 7.5 indicates high severity, but the unavailability of EPSS data makes precise quantitative risk assessment difficult. The vulnerability is not listed in CISA KEV, indicating no known exploit activity at this time. The likely attack vector is web-based, requiring only that an attacker can reach the plugin’s REST API and that the site renders translations server‑side.

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade GPTranslate to version 2.34.14 or later to eliminate the vulnerability.
  • If an upgrade is not immediately possible, disable server‑side translation storage or block the REST API endpoints used for storing translations.
  • Apply a Content‑Security‑Policy that restricts the execution of scripts to trusted origins, and ensure your web application firewall blocks suspicious XSS payloads.
