Name of the Vulnerable Software and Affected Versions Smartcat Translator for WPML versions prior to 3.1.78

Description The plugin is subject to unauthorized data modification because of a missing capability check on the 'routeData' REST endpoint. This flaw allows unauthenticated attackers to overwrite API credentials, including account ID, API secret key, hub key, API host, and hub host. Such an action can lead to the hijacking of the translation service or a denial of service.

Recommendations Update to a version later than 3.1.77. As a temporary workaround, restrict access to the 'routeData' REST endpoint to minimize the risk of exploitation.
