CVE-2025-62484Network attack vector

Privilege escalation via inefficient regular expression

Published Nov 13, 2025 · Updated Feb 26, 2026

Inefficient regular expression complexity in Zoom Workplace before 6.5.10 allows remote attackers to escalate privileges via network input. Zoom identifies an inefficient regular expression but does not disclose the affected parser, pattern, or network input that reaches it. Exploitation requires user interaction and affects only the iOS and Android clients; the published impact is confidentiality and integrity, not availability.
