CVE-2026-102569 in ClipBucket
Summary
by MITRE • 09/29/2026
ClipBucket v5 through 5.5.3-#197 contains a time-based blind SQL injection vulnerability in the admin video edit function where the videoid parameter is concatenated into an UPDATE statement without proper escaping. An authenticated administrator with video_moderation permission can inject arbitrary SQL commands to extract or modify database contents.

ClipBucket versions 5 through 5.5.3-#197 are affected by a critical time-based blind SQL injection vulnerability located within the administrative interface, specifically in the video editing functionality. This security flaw arises from improper input validation and sanitization practices when handling user-supplied data. The application fails to properly escape or parameterize the videoid parameter before incorporating it into an SQL UPDATE statement executed against the backend database. Because the input is directly concatenated into the query structure without adequate safeguards, an attacker can manipulate the syntax of the underlying SQL command, thereby altering its intended execution logic and gaining unauthorized access to data manipulation capabilities that should be restricted by application-level controls.
The operational impact of this vulnerability is significant for any deployment where authenticated administrators possess video moderation privileges. While the requirement for authentication might seem like a mitigating factor, it restricts the attack surface only to individuals who have already gained valid credentials or can exploit other vulnerabilities such as credential stuffing or session hijacking to assume an administrative role with specific permissions. Once inside this privileged context, an attacker can inject arbitrary SQL commands that leverage time-based blind techniques. This method allows for the extraction of sensitive database contents by observing response times from the server, enabling the systematic retrieval of data character by character without direct error messages being displayed in the application interface.
From a technical classification perspective, this vulnerability aligns with CWE-89, which describes Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The specific exploitation technique employed falls under ATT&CK tactic T1053, Scheduled Task/Job, or more accurately within the data exfiltration phase using techniques like T1074 or general database access methods such as T1213 if considering broader context, but primarily it represents a classic injection flaw allowing for unauthorized data modification and extraction. The blind nature of the attack means that traditional error-based detection mechanisms may fail to identify the intrusion immediately, making proactive monitoring and input validation critical defenses against this type of exploitation.
To mitigate this vulnerability, developers must implement strict parameterized queries or prepared statements for all database interactions involving user-supplied inputs. This ensures that data is treated strictly as values rather than executable code within SQL commands. Additionally, implementing robust input validation routines that reject unexpected characters and enforcing the principle of least privilege can reduce the risk surface. For existing deployments, applying vendor-provided patches to update ClipBucket beyond version 5.5.3-#197 is essential. Organizations should also review their authentication mechanisms and monitor administrative logs for anomalous activity patterns indicative of SQL injection attempts, such as unusual delays in response times or unexpected database query structures.
