# CVE-2021-22054: Omnissa Workspace ONE Server-Side Request Forgery

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Omnissa Workspace One UEM. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-03-09, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-03-23 ; treat that as the outer limit, not the target.
- EPSS 99.7% , percentile 100.0: FIRST’s model estimates a 99.7% chance of exploitation activity in the next 30 days, higher than 100.0% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

## What it is

VMware Workspace ONE UEM console 20.0.8 prior to 20.0.8.37, 20.11.0 prior to 20.11.0.40, 21.2.0 prior to 21.2.0.27, and 21.5.0 prior to 21.5.0.37 contain an SSRF vulnerability. This issue may allow a malicious actor with network access to UEM to send their requests without authentication and to gain access to sensitive information.

## Affected products (CVE record)

- n/a VMware Workspace ONE UEM console: VMware Workspace ONE UEM console 20.0.8 prior to 20.0.8.37, 20.11.0 prior to 20.11.0.40, 21.2.0 prior to 21.2.0.27, and 21.5.0 prior to 21.5.0.37.

## Severity

- CISA-ADP CVSS 3.1: 7.5 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N`

## Exploitation

- CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 99.68% probability of exploitation activity in the next 30 days; percentile 100.0.
