Ivanti Endpoint Manager Mobile (EPMM) vulnerability
Ivanti Endpoint Manager Mobile contains a code injection vulnerability in its API component allowing authenticated attackers to execute arbitrary code through crafted requests exploiting insecure Hibernate Validator usage.
Verdict
Today item — known-exploited.
An authenticated attacker can inject and execute arbitrary code on affected EPMM systems via malicious API requests. The vulnerability stems from improper validation handling in the Hibernate Validator integration, enabling remote code execution with active exploitation observed in the wild.

01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
50 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-05-19).
Probability (EPSS)
EPSS 0.86519 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) · Affected: Ivanti, Endpoint Manager Mobile (EPMM). Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
Weakness (CWE)
Mapped to CWE-94 Code Injection — weakness family: Injection.CWE — CNA-assigned (CVE.org); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 6 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious API request containing code injection payloads targeting the Hibernate Validator validation logic.
Business
Attackers gain remote code execution capability on mobile endpoint management infrastructure, risking complete system compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I send the crafted request to the EPMM API endpoint as an authenticated user or through compromised credentials.
Business
The attack bypasses application logic controls, allowing unauthorized command execution within the trusted management platform.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary code with the privileges of the EPMM service process.
Business
Attackers can access sensitive mobile device management data, manipulate device policies, or pivot to connected enterprise systems.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
