This CVE references a Java Expression Language injection vulnerability in Ivanti EPMM, which allows a user with access to a particular API to execute arbitrary code.
In conjunction with CVE-2025-4427 - an auth bypass vulnerability which gives access to the API in question - this can be used by an unauthenticated attacker.
More information on exact vulnerable versions can be found here - you should patch immediately if vulnerable. Note that in the recommended deployment of EPMM, where the API is not accessible to the internet, the impact is reduced.
