This vulnerability in VK All in One Expansion Unit allows stored cross-site scripting due to improper input neutralization during web page generation. An attacker with low privileges can inject malicious scripts that execute when viewed by other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The issue affects all versions up to 9.113.3. There is no vendor advisory or patch currently available, and no known active exploitation has been reported.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected application, potentially allowing attackers to steal sensitive information, manipulate content, or disrupt service availability. The CVSS vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change, with low confidentiality, integrity, and availability impacts.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit exposure by restricting user privileges and carefully validating or sanitizing inputs where possible. Monitor for updates from the vendor regarding official patches or mitigations.
