CVE-2026-1603Known exploitationNetwork attack vector

Credential disclosure via weak AuthHelper authentication path

Published Feb 10, 2026 · Updated Feb 10, 2026

Authentication bypass in Ivanti Endpoint Manager before 2024 SU5 allows remote attackers to disclose specific stored credential data. The AuthHelper class accepts an alternate weak authentication path instead of enforcing the normal authentication mechanism. Exploitation requires no credentials or user interaction and exposes stored credentials without reported modification or service interruption.
