About Progress LoadMaster
CVE-2026-8037 affects Progress LoadMaster, a product from Progress. Before acting, confirm where Progress LoadMaster runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: 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
The weakness class is Command Injection. Untrusted input ends up inside a system command.
Based on its CVSS vector, the flaw needs local or adjacent access, needs no login, and needs no user interaction. It is listed in the CISA Known Exploited Vulnerabilities catalog, so treat it as an active threat and patch immediately.
