CVE-2026-58001 in AVideo
Summary
by MITRE • 08/22/2026
WWBN AVideo through commit 9c39d8c8 contains a cross-site request forgery vulnerability in objects/videoEditLight.php that lacks request authenticity checks and accepts GET requests. Attackers can store an img tag in a video description that transfers video ownership to an attacker-controlled account when an administrator views the video page.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The identified vulnerability represents a critical cross-site request forgery flaw within WWBN AVideo, specifically located in the objects/videoEditLight.php component prior to commit 9c39d8c8. This security defect stems from a fundamental failure in implementing proper authentication and authorization controls for state-changing operations. The application accepts GET requests for actions that modify significant system data, which violates standard web development practices where GET methods should be idempotent and safe, meaning they should not alter the server's state. Furthermore, the endpoint lacks request authenticity checks such as anti-CSRF tokens or strict origin validation mechanisms. This architectural oversight allows an attacker to craft malicious requests that can be executed by a victim user who is authenticated with elevated privileges, effectively bypassing intended access controls through social engineering techniques rather than technical exploitation of code logic flaws in isolation.
The operational impact of this vulnerability is severe due to its potential for account takeover and data manipulation within the video management platform. An attacker can exploit this flaw by embedding a malicious HTML img tag into a video description field, which serves as a stored cross-site scripting vector that triggers the CSRF payload when viewed. When an administrator or any user with sufficient permissions views the compromised video page, their browser automatically sends the forged GET request to the vulnerable endpoint because it includes valid session cookies. This action results in the unauthorized transfer of video ownership from the legitimate owner to an account controlled by the attacker. Such a capability undermines data integrity and confidentiality, allowing attackers to hijack content, potentially distribute malicious media under trusted accounts, or use the compromised videos for further phishing campaigns against other users on the platform.
From a classification perspective, this vulnerability aligns with CWE-352 Cross-Site Request Forgery (CSRF), which describes situations where an application uses user credentials without verifying that the request was intentionally made by the user. Additionally, it relates to CWE-614 Sensitive Cookie in HTTPS Session Without HttpOnly Flag if session cookies are not properly secured against client-side script access, although the primary issue is the lack of CSRF protection. In terms of offensive security frameworks, this attack vector corresponds to MITRE ATT&CK technique T1556.003 Modifying Authentication Process via Cross-Site Request Forgery, where adversaries manipulate user interactions to perform actions on behalf of authenticated users without their knowledge or consent. The combination of stored input validation failure and missing CSRF tokens creates a high-severity risk profile that requires immediate remediation to prevent unauthorized administrative actions.
To mitigate this vulnerability, developers must implement robust anti-CSRF measures across all state-changing endpoints within the AVideo application. This includes generating unique, unpredictable per-user session tokens that are validated on every POST or GET request intended to modify data. The objects/videoEditLight.php endpoint should be restricted to accept only POST requests for edit operations, adhering to RESTful principles and preventing simple link-based attacks via img tags. Additionally, implementing strict SameSite cookie attributes can provide an additional layer of defense by instructing browsers not to send cookies in cross-site contexts unless explicitly allowed. Input validation must also be strengthened to sanitize or encode HTML content within video descriptions to prevent the execution of malicious scripts that trigger these forged requests. Regular security audits and code reviews focusing on authentication flows are essential to ensure such gaps do not persist in future releases, thereby maintaining the integrity and trustworthiness of the platform for all administrators and users.
