User impersonation via improper SAML signature validation
Published Aug 13, 2026 · Updated Aug 13, 2026
Authentication bypass in ManageEngine Password Manager Pro before 13232 and PAM360 before 8551 lets remote authenticated users impersonate any user. The SAML authentication path improperly verifies cryptographic signatures on assertions, so a signed-in user can be accepted under another user's identity. Exploitation requires an authenticated account and grants the target user's access, including any privileges and protected data assigned to that identity.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
