This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the site's Player Library option to be configured as Plyr/Vidstack (aiovg_player_settings[player]='vidstack') rather than the Video.js default, as the DOM innerHTML sink exists only in the Plyr/Vidstack template path.\n\n## Affected\n\n- `all-in-one_video_gallery_video_player_galleries_for_youtube_vimeo_self-hosted_videos <= 5.0.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
