Ivanti Endpoint Manager Mobile (EPMM) Code Injection Vulnerability
CVE-2025-4428 is a security vulnerability in Ivanti Endpoint Manager Mobile (EPMM), added to CISA KEV on May 19, 2025. Patch priority: Patch this week.
What it is
Ivanti Endpoint Manager Mobile (EPMM) contains a code injection vulnerability in the API component that allows an authenticated attacker to remotely execute arbitrary code via crafted API requests. This vulnerability results from an insecure implementation of the Hibernate Validator open-source library, as represented by CVE-2025-35036.
VulnCheck tracked exploitation 6 days before CISA's KEV listing. VulnCheck's broader catalog of in-the-wild exploitation evidence picked this up before it landed on CISA's formal list. Per-CVE fact about this entry; not a population claim about lead time in general.
Who's affected
Affects anyone using Ivanti VPN (Connect Secure or Pulse) or Ivanti endpoint management. The VPN is what remote workers use to reach internal systems; the endpoint management tool typically has admin reach into every laptop — exploitation in either is high-impact.
What to do
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Insurance readiness
Your insurer will ask if this is patched.
Unpatched entries on CISA's Known Exploited Vulnerabilities list are exactly what cyber-insurance carrier questionnaires probe for, and knowing which controls they check is how you keep a renewal from stalling.

CISA due date
Federal deadline: June 9, 2025. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
EPSS
EPSS score: 85.3% — higher than 100% of all scored CVEs.
EPSS estimates the probability of exploitation activity in the next 30 days. Every entry on this site is already confirmed exploited, so read it as relative urgency among the things you still have open, not as permission to wait.
