Protected CLI execution via unrecognized PowerShell wrapper
Published Jul 19, 2026 · Updated Jul 19, 2026
Improper authorization in GoClaw 3.13.3-beta.0 through 3.13.3-beta.3 allows remote authenticated users to run protected CLIs. ExecTool.Execute treats pwsh and powershell as ordinary binaries, so the secure-CLI gate never decodes -EncodedCommand input to inspect the registered inner executable. Operator-level access to the direct exec tool and a PowerShell host path are required; exploitation runs credential-backed commands without the required agent grant.
