Ivanti Endpoint Manager Mobile (EPMM) vulnerability
Ivanti Endpoint Manager Mobile (EPMM) contains an authentication bypass vulnerability in its API component that allows attackers to access protected resources without proper credentials through crafted requests.
Verdict
Today item — known-exploited.
An insecure Spring Framework implementation in EPMM's API enables unauthenticated access to protected resources. The vulnerability is actively exploited in the wild with high exploit probability, posing immediate risk to organizations running affected versions.

Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-05-19).
Probability (EPSS)
EPSS 0.99589 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Ivanti, Endpoint Manager Mobile (EPMM). Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-288 Auth Bypass via Alternate Path — weakness family: Authentication.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
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 malicious API requests that bypass authentication controls to gain unauthorized access to the EPMM system.
Business
Attackers gain direct access to mobile device management infrastructure, enabling potential compromise of managed endpoints and sensitive organizational data.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I enumerate and extract configuration data, user credentials, and device information from the compromised EPMM instance.
Business
Loss of confidentiality across mobile device inventory, user accounts, and enterprise security policies creates exposure for lateral movement and data exfiltration.
3
Lateral reach — past segmentation narrative 3
Attacker
I modify device policies, disable security controls, or inject malicious configurations to compromise managed mobile devices at scale.
Business
Integrity of mobile device security posture is compromised, enabling widespread endpoint compromise and potential supply chain attacks through trusted devices.
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.
