## Technical details

Multiple vulnerabilities in Zscaler Client Connector allow local privilege escalation (LPE) attacks. The vulnerabilities enable unprivileged local users to execute arbitrary code in a privileged context, typically through a flaw in how the application handles permissions or processes. Attack preconditions require local access to the affected system. An attacker with a standard user account can gain administrative or system privileges, leading to full device compromise. Fixes are expected in patched versions; users should check Zscaler's release notes for the specific affected versions and available patches.
