CVE-2026-33770 is a high-severity SQL injection vulnerability affecting WWBN AVideo, an open-source video platform. The vulnerability arises from the `fixCleanTitle()` static method in `objects/category.php`, which constructs a SQL SELECT query by directly interpolating user inputs without utilizing prepared statements or parameterized queries. This design flaw allows an attacker who can trigger category creation or renaming with a crafted title value to inject arbitrary SQL into the application.
The vulnerability has a CVSS v4.0 base score of 7.1, indicating a high severity level. The attack vector is network-based, and the attack complexity is low, meaning exploitability is relatively straightforward. There are no special user interactions required, and the attacker only needs low privileges to execute the exploit. This vulnerability poses a significant risk to confidentiality, as unauthorized access to sensitive data could occur.
Organizations using AVideo versions up to and including 26.0 are at risk. The vulnerability was published on March 27, 2026, and patched in commit 994cc2b3d802b819e07e6088338e8bf4e484aae4. Given the potential impact of this vulnerability, organizations should prioritize patching immediately to mitigate risks.
Risk to organizations includes unauthorized access to sensitive data and potential data manipulation. Therefore, it is essential to assess the deployment of AVideo and implement necessary patches as soon as possible.
Vulnerability Details
The CVE-2026-33770 vulnerability allows attackers to inject arbitrary SQL through the `fixCleanTitle()` method, which fails to properly sanitize inputs. With a CVSS v3.1 base score of 9.8, this vulnerability is classified as critical due to its potential impact on confidentiality, integrity, and availability.
The affected product is WWBN AVideo, with versions up to and including 26.0 being vulnerable. The vulnerability was publicly disclosed on March 27, 2026, and it is categorized under CWE-89, which refers to SQL Injection vulnerabilities.
Technical Analysis
The root cause of CVE-2026-33770 lies in the improper handling of user input in SQL queries. The `fixCleanTitle()` method directly interpolates user inputs into SQL statements without any form of sanitization or parameterization, making it susceptible to SQL injection attacks.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability. The attack complexity is low, as it does not require specific conditions or high-level privileges to execute. No user interaction is required, which increases the risk of exploitation.
Regarding impact, the vulnerability poses a high confidentiality risk as it allows unauthorized access to potentially sensitive data stored in the application's database. Integrity and availability impacts are classified as none, given the nature of the exploit.
Risk & Impact Analysis
Real-world deployment of this vulnerability can lead to severe consequences for organizations utilizing WWBN AVideo. The high potential for unauthorized data access and manipulation highlights the critical nature of this vulnerability.
Given the CVSS score of 9.8, organizations should place this vulnerability at the top of their remediation priorities. The urgency for addressing this vulnerability is underscored by its potential for exploitation across network environments.
Organizations should implement effective monitoring to identify any unusual database queries or patterns indicative of exploitation attempts. Additionally, the blast radius for this vulnerability can be significant if left unaddressed, as it allows attackers to compromise the entire system.
