About Ivanti Endpoint Manager (EPM)
CVE-2026-1603 affects Ivanti Endpoint Manager (EPM), a product from Ivanti. Before acting, confirm where Ivanti Endpoint Manager (EPM) runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: An authentication bypass in Ivanti Endpoint Manager before version 2024 SU5 allows a remote unauthenticated attacker to leak specific stored credential data.
The weakness class is Authentication Bypass via Alternate Path. A second route into the app skips the login check.
Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. It is listed in the CISA Known Exploited Vulnerabilities catalog, so treat it as an active threat and patch immediately.
