In versions 1.11.3 and prior, the middleware functionality in Hoverfly is vulnerable to command injection vulnerability at /api/v2/hoverfly/middleware endpoint due to insufficient validation and sanitization in user input. The vulnerability exists in the middleware management API endpoint /api/v2/hoverfly/middleware. This issue is born due to combination of three code level flaws: Insufficient Input Validation in middleware.go line 94-96; Unsafe Command Execution in localmiddleware.go line 14-19; and Immediate Execution During Testing in hoverflyservice.go line 173. This allows an attacker to gain remote code execution (RCE) on any system running the vulnerable Hoverfly service. Since the input is directly passed to system commands without proper checks, an attacker can upload a malicious payload or directly exe...", "creation_timestamp": "2026-08-27T15:00:11.230060Z"}
