CVE-2025-30664

Local privilege escalation via cross-site scripting

Published May 14, 2025 · Updated Feb 26, 2026

Cross-site scripting in Zoom Workplace Apps allows local authenticated users to escalate privileges through local access and user interaction. Zoom has not disclosed the affected component, the special elements that are insufficiently neutralized, or the rendering path that executes injected script. Exploitation requires an authenticated local user and user interaction, and successful abuse raises that user's privileges without requiring network reachability.
