Inefficient regular expression complexity (ReDoS) in Zoom Workplace Client and Zoom Meeting SDK builds for Android and iOS earlier than 6.5.10 allows a remote, unauthenticated attacker to force the client to process crafted input through a vulnerable regular-expression code path, causing excessive CPU consumption and potential client unavailability; no user interaction is required per the CVSS vector (AV:N/PR:N/UI:N). The NVD score of 9.8 (C:H/I:H/A:H) overstates impact relative to the underlying CWE-1333 weakness - our independent assessment re-scores this as availability-only (C:N/I:N/A:H) - and the public description's claim of 'escalation of privilege' is not supported by the ReDoS root cause; treat the privilege-escalation framing with caution. There is no confirmed active exploitation (not in CISA KEV), no public exploit code identified at time of analysis, and EPSS is low at 0.12% (31st percentile), indicating limited near-term exploitation likelihood despite the high headline score.
Privilege escalation in Zoom Workplace for Android (and the Zoom Meeting Software Development Kit for Android) before version 6.5.10 allows remote attackers to gain elevated privileges, with a vendor-assigned CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reflecting high confidentiality, integrity and availability impact and no authentication, privileges or user interaction required in the vector. The practical constraint is reachability: because the affected component is a mobile client rather than a listening service, an attacker must be able to place the device on hostile or shared infrastructure or induce it to talk to a malicious endpoint before the flaw can be exercised. Exploitation activity is not confirmed, no public exploit code has been identified at time of analysis, and EPSS is low at 0.15% (35th percentile), which is consistent with a high-severity but not yet operationalized flaw. The only public reference is the Zoom security bulletin ZSB-25043.
