FKIE_CVE-2024-6541
Vulnerability from fkie_nvd - Published: 2026-08-06 22:16 - Updated: 2026-08-07 18:17
Severity
Summary
The Class Mediator fails to correctly validate or sanitize `messageContext` properties when they are used to populate dynamic values. This allows authenticated users to potentially access or modify data across different system invocations that should be isolated.
This weakness can lead to the disclosure of sensitive information belonging to other users or the unintended modification of system data by authenticated users. The exact impact depends on how `messageContext` properties are utilized within the affected WSO2 products.
