Security audit
Security checks for vulnerabilities and agentic risk
This profiling skill needs review because its troubleshooting instructions weaken host security and its verification example can erase previous results.
Before use, remove the SELinux-disabling and world-writable-directory workarounds, use a private output directory, and replace automatic deletion with a fresh directory per run. Run only a trusted operator under ordinary user permissions. The referenced analysis script is missing and needs separate review if supplied later. These concrete concerns justify Review; the scanner's critical rating alone does not establish malicious intent.
references/troubleshooting.mdPermission troubleshooting disables host-wide SELinux enforcement
SELinux policy denials stop blocking operations throughout the host, allowing otherwise-confined processes to perform actions still permitted by discretionary permissions. The instructions provide no restoration step.
references/troubleshooting.mdProfiling output directory is made writable by every local user
Other local users can plant misleading output entries or rename and remove profiling entries regardless of individual file write permissions, compromising profiling-output integrity and availability.
Making the operator executable is a plausible supporting implementation detail. However, setenforce 0 disables SELinux enforcement system-wide when run with sufficient privileges. This security-policy change is materially broader than the declared profiling functionality and is not disclosed in the description. Its conditional troubleshooting framing does not change the command's effect.
The recommended setenforce 0 command puts SELinux into permissive mode system-wide if executed with sufficient privileges, removing mandatory access-control enforcement beyond the profiling process. A routine profiling permission error does not justify weakening isolation for every workload on the host.
The text labels disabling SELinux as temporary but provides neither a system-wide impact warning nor a restoration step. An agent or operator following this troubleshooting advice could leave unrelated services without SELinux enforcement after profiling ends.
The chmod 777 parameter grants all local users write access to the profiling directory, although profiling normally requires access only for its executing user. This is an unsafe permission workaround rather than evidence of malicious tool use, with risks primarily involving local output tampering and deletion.
mkdir -p /tmp/profiling chmod 777 /tmp/profiling
### Issue: CSV files missing
Making the predictable /tmp/profiling directory mode 777 permits other local users to list its entries and create, remove, or replace directory entries. This can compromise profiling-output integrity and availability; file-content disclosure additionally depends on individual file permissions.
The verification script recursively deletes output_npu relative to its current working directory without checking whether it contains valuable prior results or requesting approval. Although the target is bounded rather than arbitrary, running this routine verification can irreversibly destroy existing profiling artifacts.
