CVE-2026-92993
Dromara mayfly-go Machine Script Feature machine_script.go RunMachineScript os command injection
Description

A vulnerability was detected in Dromara mayfly-go up to 1.11.5. The impacted element is the function RunMachineScript of the file server/internal/machine/api/machine_script.go of the component Machine Script Feature. The manipulation of the argument params results in os command injection. The attack can be executed remotely. The exploit is now public and may be used. Exploitation needs no admin account. Any account holding machine:script:run plus tag access reaches arbitrary command execution on machines whose templates contain {{.param}} placeholders; the SSH exec layer (Cli.Run) also applies no input filtering to any caller. The vendor was contacted early about this disclosure but did not respond in any way.

Solution
Remediate OS command injection by sanitizing input and updating the software.
  • Sanitize all user-provided input for params.
  • Update Dromara mayfly-go to a patched version.
  • Review machine templates for {{.param}} placeholders.
  • Restrict access to machine:script:run capability.
