Action Type Old Value New Value Changed Description A vulnerability has been identified in Mendix Runtime (All versions). Mendix documentation for access rules does not adequately describe the special behavior of the System.User entity, leaving developers without sufficient guidance to configure access rules securely. This documentation gap may lead application developers to unknowingly apply overly permissive access rules to System.User, resulting in unintended exposure of sensitive user data or privilege escalation within deployed Mendix applications. Rejected reason: This CVE has been retracted. Re-investigation confirmed the reported behavior is expected platform configuration and does not expose the protected attribute.

Action Type Old Value New Value Added Affected [{'vendor': 'Siemens', 'product': 'Mendix Runtime', 'versions': [{'status': 'affected', 'version': '0', 'lessThan': '*', 'versionType': 'custom'}], 'defaultStatus': 'unknown'}] Changed Description The VerySecureApp made by DIVD using Mendix Studio Pro 11.8.0 Beta allows unintended data exposure due to authorization misconfiguration. The VerySecureApp allows anonymous users of the MyFirstModule with the anonymous user role to gain access to all stored records, even though no access rights are explicitly configured on that role. Anonymous users are required to make a Mendix Entity available publicly.
