CVE-2026-45418
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. Prior to version 5.5.3 - #132, any authenticated user who can upload videos can add multiple subtitles from different files and change their title (English, Spanish...). The POST /actions/subtitle_edit.php request used to change their title includes a number parameter which is vulnerable to SQL Injection. A boolean-based blind SQL injection can be used to exfiltrate sensitive data. This issue has been patched in version 5.5.3 - #132.
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 analysis · high confidenceClipBucket v5 prior to version 5.5.3 contains an authenticated blind SQL injection in the POST /actions/subtitle_edit.php endpoint. The 'number' parameter used when changing subtitle titles is not properly sanitized, allowing any authenticated user with video upload privileges to exfiltrate sensitive data from the database via boolean-based blind SQLi.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed ClipBucket versionLocate the version number in the ClipBucket installation - check the admin dashboard version display, a version.php file in the root directory, or the database version记录Affected if The installed version is 5.x prior to version 5.5.3 (any 5.0 through 5.5.2 is affected)
-
Verify vulnerable endpoint existsConfirm the file /actions/subtitle_edit.php exists in the web accessible directoryAffected if The file exists and responds to POST requests
-
Review user accounts with video upload accessCheck user accounts and their group permissions in the ClipBucket admin panel or database - look for users assigned to groups with video upload or subtitle editing privilegesAffected if There are user accounts with video upload privileges that are not fully trusted or are accessible to untrusted personnel
-
Test parameter handling in subtitle_edit.phpSubmit a POST request to /actions/subtitle_edit.php with a test value in the 'number' parameter and observe if it is processed without sanitization or triggers SQL errorsAffected if The 'number' parameter accepts raw input and the application does not sanitize or parameterize the value before using it in a database query
You are affected if your ClipBucket installation is version 5.0 through 5.5.2, the subtitle_edit.php endpoint exists, and you have any authenticated user with video upload privileges that could access the vulnerable parameter.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to ClipBucket v5.5.3 or later (patch #132) which addresses the SQL injection vulnerability. As a temporary measure, restrict video upload permissions to trusted users only until the patch can be applied.
ClipBucket v5.5.3
- 1. Backup your current ClipBucket installation and database before upgrading.
- 2. Download ClipBucket version 5.5.3 or later from the official repository (github.com).
- 3. Replace the existing files with the new version, preserving your configuration and upload directories.
- 4. Verify that /actions/subtitle_edit.php has been updated with parameterized queries to prevent SQL injection.
- 5. Test the subtitle editing functionality to confirm the fix works correctly.
- 6. Ensure that only trusted users have subtitle upload/edit permissions as a defense-in-depth measure.
