Summary

ClipBucket v5 is an open source video sharing platform. Versions 5.5.2-#147 and below contain a stored Cross-Site Scripting (XSS) vulnerability in ClipBucket’s Collection tags feature. An authenticated normal user can create a tag containing HTML or JavaScript, which is later rendered unescaped in collection detail and tag-list pages. As a result, arbitrary JavaScript executes in the browsers of all users who view the affected pages. This issue is fixed in version 5.5.2-#152.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
