**Name of the Vulnerable Software and Affected Versions** Overwolf Client version 0.169.0.22 **Description** The issue allows for XSS, resulting in Remote Code Execution, via an `overwolfstore://` URL. There is no information provided about the estimated number of potentially affected devices worldwide or details about real-world incidents where this issue was exploited. **Recommendations** For Overwolf Client version 0.169.0.22, update to a version that fixes the XSS vulnerability to prevent Remote Code Execution via `overwolfstore://` URLs. As a temporary workaround, consider restricting access to `overwolfstore://` URLs until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Revive Adserver versions prior to 3.2.5 Revive Adserver versions prior to 4.0.0 **Description** The issue concerns Special Element Injection due to improper sanitization of usernames when creating users on a Revive Adserver instance. Specifically, control characters were not filtered, allowing multiple usernames that appear identical to co-exist in the system. This could be exploited for user spoofing, although it requires elevated privileges to create users within Revive Adserver. **Recommendations** For Revive Adserver versions prior to 3.2.5, update to version 3.2.5 or later. For Revive Adserver versions prior to 4.0.0, update to version 4.0.0 or later.
