CVE-2026-53413: CWE-787 Out-of-bounds write in Zoom Communications Zoom Clients
Missing bounds check in the annotator function of Zoom Clients allows buffer over-write, which may allow a meeting participant to achieve remote code execution of another participant via network access.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-53413) in Zoom Clients is caused by a missing bounds check in the annotator function, leading to an out-of-bounds write (CWE-787). Exploitation could allow a remote attacker, who is a participant in a Zoom meeting, to achieve remote code execution on another participant's client via network access. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, and a scope change with high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to remote code execution on a victim's Zoom client, compromising confidentiality, integrity, and availability of the affected system. This could allow an attacker to execute arbitrary code remotely during a Zoom meeting session.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is currently available. Users and administrators should monitor Zoom Communications' advisories for updates and apply patches promptly once released.
