CVE-2023-43586Network attack vector

Privilege escalation via untrusted search path

Published Dec 13, 2023 · Updated Feb 25, 2026

Path traversal in Zoom Windows desktop, VDI, and SDK products allows remote authenticated users to escalate privileges via network access. Zoom identifies an untrusted search path but has not disclosed the affected component, attacker-controlled path, or searched resource. Exploitation requires high privileges, user interaction, and high-complexity network conditions; success crosses a privilege boundary with confidentiality and integrity impact.
