Orta CVSS 5.4
CVE-2026-55491: CVE-2026-55491: siteler arası betik çalıştırma (XSS)
Açıklama (NVD)
BigBlueButton is an open-source virtual classroom. Prior to 3.0.29, BigBlueButton failed to escape meetingName in record-and-playback/screenshare/playback/index.html.erb when generating the screenshare playback format. A low-privileged user could store a crafted meeting name that embedded script content, and the script executed in another user's browser when that user replayed the recording. This issue is fixed in version 3.0.29.
