7.3

High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L

Name of the Vulnerable Software and Affected Versions picoclaw versions prior to 0.1.3

Description The ExecTool component (pkg/tools/shell.go) allows OS command injection. This occurs because the guardCommand() function uses an incomplete denylist of eight regular expressions to restrict shell command execution, failing to block all malicious inputs.

Recommendations Update picoclaw to a version later than 0.1.2. As a temporary workaround, restrict the use of the guardCommand() function within the ExecTool component.
