CVE-2025-48366

Name of the Vulnerable Software and Affected Versions Group-Office versions prior to 6.8.119 and 25.0.20

Description A stored and blind XSS issue exists in the Phone Number field of the user profile within the Group-Office application. This allows a malicious actor to inject persistent JavaScript payloads, which are triggered in the context of another user when they view the Address Book. Successful exploitation enables actions such as forced redirects, unauthorized fetch requests, or other arbitrary JavaScript execution without user interaction.

Recommendations For versions prior to 6.8.119, update to version 6.8.119 or later. For versions prior to 25.0.20, update to version 25.0.20 or later.
