Summary
by MITRE • 10/23/2026
WWBN AVideo before 29.4.0 contains an incorrect authorization vulnerability that allows delegated Users Admin accounts to delete or modify administrator accounts. Attackers can submit requests to confirmDeleteUser.json.php or userAddNew.json.php targeting administrators to delete their videos and accounts, or change and demote them.

The vulnerability identified in WWBN AVideo versions prior to 29.4.0 represents a critical failure in access control mechanisms, specifically categorized under CWE-862: Missing Authorization. This flaw allows delegated Users Admin accounts, which are intended to have limited privileges compared to full system administrators, to perform actions that should be restricted exclusively to super-administrators. The core technical issue lies in the insufficient validation of user roles and permissions when processing requests related to account management. Specifically, the application fails to verify whether the authenticated user possesses the necessary hierarchical authority before executing sensitive operations on other accounts, particularly those belonging to administrators.
The operational impact of this vulnerability is severe, as it enables an attacker with a delegated admin role to escalate their privileges effectively by manipulating or removing higher-level administrative users. By submitting crafted requests to endpoints such as confirmDeleteUser.json.php and userAddNew.json.php, the attacker can target existing administrator accounts. This capability allows for the deletion of videos associated with these accounts, complete removal of the administrator profiles from the system, or modification of their roles to demote them to lower privilege levels. Such actions disrupt service availability by removing key personnel responsible for platform management and compromise data integrity by altering user configurations without proper authorization checks.
From a threat modeling perspective, this vulnerability aligns with MITRE ATT&CK technique T1078: Valid Accounts, where an attacker uses legitimate credentials that have been misused due to poor access control policies. The ability to delete or modify administrator accounts falls under the broader category of privilege escalation and account manipulation tactics often seen in lateral movement phases of cyber attacks. By eliminating administrative oversight, attackers can maintain persistent access to the platform without detection, potentially using the compromised system for further malicious activities such as hosting illegal content or launching additional attacks against users.
Mitigation strategies must focus on implementing strict role-based access control (RBAC) principles within the application logic. Developers should ensure that all endpoints handling user management operations explicitly check the requester's role against a predefined list of allowed roles before proceeding with any state-changing actions. For organizations currently running affected versions, immediate upgrading to version 29.4.0 or later is required as this release addresses the authorization checks in the specified JSON PHP files. Additionally, implementing principle of least privilege for all delegated admin accounts and auditing access logs regularly can help detect unauthorized attempts to modify administrative structures before they result in significant damage.
