CVE-2025-64338
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedClipBucket v5 is an open source video sharing platform. In versions 5.5.2 - #156 and below, an authenticated regular user can create a photo collection whose Collection Name contains HTML/JavaScript payloads, which making ClipBucket’s Manage Photos feature vulnerable to Stored XSS. The payload is rendered unsafely in the Admin → Manage Photos interface, causing it to execute in the administrator’s browser, therefore allowing an attacker to target administrators and perform actions with elevated privileges. This issue is fixed in version 5.5.2 - #157.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUntrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

dbcve · scoped5.5.2-157
5.5.2-#157 or latest stable release after this version
- 1. Backup the entire ClipBucket installation directory and database before making any changes
- 2. Navigate to the official ClipBucket repository at https://github.com/MacWarrior/clipbucket-v5
- 3. Download version 5.5.2-#157 or later from the releases page
- 4. Extract the new version and replace the existing files on the server, preserving configuration files (config.php or similar)
- 5. Clear any application caches if available
- 6. Verify the fix by logging in as a regular user, creating a test photo collection with an XSS payload in the name (e.g., <script>alert('XSS')</script>)
- 7. Navigate to Admin → Manage Photos and confirm the payload is no longer executed/rendered as raw HTML
- 8. Test that legitimate HTML in collection names is now properly escaped or sanitized
