Commvault

A local privilege escalation vulnerability exists in Commvault for Windows versions 11.20.0, 11.28.0, 11.32.0, 11.34.0, and 11.36.0. In affected configurations, a local attacker who owns a client system with the file server agent installed can compromise any assigned Windows access nodes. This may allow unauthorized access or lateral movement within the backup infrastructure. The issue has been resolved in versions 11.32.60, 11.34.34, and 11.36.8.
