# CVE-2026-8037: Progress LoadMaster Command Injection Vulnerability

**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 Progress LoadMaster. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-08-07, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-08-10 ; treat that as the outer limit, not the target.
- EPSS 77.4% , percentile 99.6: FIRST’s model estimates a 77.4% chance of exploitation activity in the next 30 days, higher than 99.6% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Editorial verdict: Check exposure. Progress LoadMaster CVE-2026-8037: Exploited Pre-Auth RCE — Only LoadMaster-based appliances with the API enabled are exposed, but for those this is unauthenticated root RCE with a public exploit; if that's you and you're below 7.2.63.2 or 7.2.54.18, patch today.

## What it is

OS Command Injection Remote Code Execution Vulnerability in API in Progress ADC Products allows an un-authenticated attacker to execute arbitrary commands on the LoadMaster appliance by exploiting unsanitized input in multiple command endpoints

## Affected products (CVE record)

- Progress Software LoadMaster: V7.2.60.0 < V7.2.63.2, V7.2.54.12 < V7.2.54.18
- Progress Software ECS Connections Manager: V7.2.60.0 < V7.2.63.2
- Progress Software Object Scale Connection Manager: V7.2.60.0 < V7.2.63.2
- Progress Software MOVEit WAF: V7.2.60.0 < V7.2.63.2

## Severity

- ProgressSoftware CVSS 3.1: 9.6 `CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2026-08-07; federal due date 2026-08-10. Known ransomware use: Unknown.
- CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 77.36% probability of exploitation activity in the next 30 days; percentile 99.6.
