Local privilege escalation in certain Zoom Clients for Windows lets an authenticated local user exploit a time-of-check to time-of-use (TOCTOU) race during install/uninstall to gain higher privileges (likely SYSTEM). The flaw was reported by Zoom's own security team and is documented in bulletin ZSB-26012; no public exploit identified at time of analysis and it is not on CISA KEV. The high-complexity race window and local-access requirement temper an otherwise high-impact (C:H/I:H/A:H) issue.
File path control in Zoom Workplace for Windows Mail feature before 6.6.0.
Zoom Client for Windows contains a privilege escalation vulnerability that allows authenticated local users to gain elevated system privileges through improper access controls.
