Vulnerability from github – Published: 2026-09-17 21:31 – Updated: 2026-09-17 21:31

Details

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.
