CVE-2026-3183 refers to a Broken Authentication vulnerability reported in ManageEngine ADSelfService Plus where incomplete enforcement of session-level authentication state checks at a sensitive API endpoint allowed an attacker with a valid user password to bypass MFA and gain unauthorized account access
This vulnerability affects builds 6523 and earlier. Any attacker with knowledge of a valid user's domain password can exploit this vulnerability to fully bypass MFA protections, gain unauthorized access to that user's ADSelfService Plus account, and take over associated privileges.
This issue has been resolved in ADSelfService Plus build 6524 by enforcing session-level authentication state checks at sensitive API endpoints, ensuring that privileged operations can only be performed by sessions that have completed MFA.
Update your ADSelfService Plus instance to build 6524 or later, using the service pack.
This issue was reported by Jake Zukowski and Damian Pajszczyk through the Zoho BugBounty program.
