Summary
CVE-2026-96272 is a blind SQL injection vulnerability in ClipBucket v5, a PHP-based video/photo sharing platform. The flaw affects the photo search endpoint, where a user-supplied query parameter is concatenated unsanitized into SQL WHERE and ORDER BY clauses. It is unauthenticated and network-exploitable, and has been assigned a high severity rating.
Technical details
- Root cause: The photo search functionality (in
photos.class.php) builds SQL queries by directly embedding thesearchquery parameter intoWHEREandORDER BYclauses without parameterization or sanitization. - Trigger conditions: An attacker sends a crafted HTTP request to the photo search endpoint (
search_result.php) with a malicious value in the search query parameter. - Attack vector: Network-based, requires no authentication and no user interaction, and has low attack complexity.
- Impact: Using time-based blind SQL injection techniques, an attacker can extract data from the underlying database, including user credentials, email addresses, and administrator password hashes — enabling account takeover and broader compromise of the application.
Affected software
- ClipBucket v5, all versions prior to 5.5.3-#182
Severity
- CVSS v4.0 Base Score: 8.7 (High) —
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N - CVSS v3.1 Base Score: 7.5 (High) —
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Mitigation and recommended actions
- Immediate: Upgrade ClipBucket v5 to version 5.5.3-#182 or later, which addresses the unsanitized query handling in the photo search endpoint.
- If no patch can be applied immediately: Restrict or disable public access to the photo search endpoint, deploy a web application firewall (WAF) rule to block SQL injection patterns in search-related parameters, and monitor database and web server logs for anomalous, time-delayed query patterns indicative of blind SQL injection probing.
