Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
