Authenticated command execution via basename-only approval cache
Published Jul 18, 2026 · Updated Jul 18, 2026
Incorrect authorization in GoClaw 3.13.0 through 3.13.2 allows remote authenticated users to execute unapproved host commands. RequestApproval stores only the outer executable basename for an allow-always decision, so distinct BusyBox shell payloads reuse the same trust entry. The path requires operator access, full security with ask-on-miss, and prior permanent approval of a BusyBox-wrapped command; later payloads run with the GoClaw process privileges.
