Contributor XSS via undisclosed input handling
Published Aug 18, 2026 · Updated Aug 18, 2026
Cross-site scripting in Video Conferencing with Zoom through 4.6.8 allows remote authenticated users to execute script via contributor content. Public records from Patchstack do not disclose the vulnerable parameter, file, or rendering sink, so the exact code path remains undisclosed. Exploitation requires authenticated Contributor access and user interaction, limiting reach to sites that let low-privileged authors supply content later viewed by other users.
