9. April 2026

The pentest professionals at usd HeroLab identified a vulnerability during a cloud pentest that allows the circumvention of conditional access policies for privileged identities in Microsoft Entra ID through the combination of role-based policy assignment and Privileged Identity Management (PIM).

Two additional vulnerabilities were identified during a web application pentest of Tenable Nessus Manager, which allow low-privileged users to read arbitrary files at the operating system level.

The vulnerabilities were reported to the vendors as part of the Responsible Disclosure Policy. Detailed information about the advisories can be found here:
