Omnissa Workspace One UEM vulnerability
Omnissa Workspace One UEM contains a server-side request forgery vulnerability allowing unauthenticated network-adjacent attackers to send arbitrary requests and access sensitive information.
Verdict
Today item — known-exploited.
An SSRF flaw in Workspace One UEM permits network-proximate adversaries to bypass authentication controls, forge internal requests, and exfiltrate confidential data. Active exploitation in the wild elevates risk despite lack of CVSS scoring.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
4 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 2026-03-09).
Probability (EPSS)
EPSS 0.97713 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Omnissa, Workspace One UEM. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-918 Server-Side Request Forgery (SSRF).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 gain network access to the UEM infrastructure and craft a malicious request exploiting the SSRF vulnerability to bypass authentication.
Business
Attackers circumvent security perimeter controls designed to protect administrative systems from unauthorized access.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I use the SSRF to send forged requests to internal services and APIs that would normally require authentication.
Business
Internal service boundaries collapse, allowing lateral movement and privilege escalation within the management infrastructure.
3
Lateral reach — past segmentation narrative 3
Attacker
I retrieve sensitive information from backend systems, configuration data, and credentials accessible through the compromised UEM.
Business
Confidential enterprise data including device management policies, user credentials, and system configurations are exposed to adversaries.
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.
