CVE-2026-16129: Incomplete Blacklist in princezuda SafestClaw
A vulnerability has been found in princezuda SafestClaw up to 4.2.4. This vulnerability affects the function ShellAction._validate_command of the file src/safestclaw/actions/shell.py of the component Built-in Web Interface. Such manipulation leads to incomplete blacklist. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The presence of this vulnerability remains uncertain at this time. The project maintainer explains: "On paper you're correct, this is a vulnerability. In practice, nothing your AI generated shows how it makes users vulnerable. It's open source. Someone can mod the shell allow list or remove that system. Present an actual poc that shows a threat to users."
AI Analysis
Technical Summary
This vulnerability affects the ShellAction._validate_command function in src/safestclaw/actions/shell.py of princezuda SafestClaw versions up to 4.2.4. It results in an incomplete blacklist that could theoretically allow unauthorized command execution. Exploitation requires local access and no user interaction. The project maintainer has stated that while the vulnerability exists in theory, no demonstrated proof-of-concept shows an actual threat to users, as the software is open source and users can modify or remove the shell allow list. There is no official remediation or patch available at this time.
Potential Impact
The vulnerability could allow local attackers to bypass the blacklist intended to restrict shell commands, potentially leading to unauthorized command execution. However, no confirmed exploits or proof-of-concept are available, and the maintainer indicates the practical risk is minimal. The CVSS 4.8 score reflects a medium severity with local attack vector and low complexity.
Mitigation Recommendations
No official patch or fix is currently available. The project maintainer suggests that the risk is mitigated by the open-source nature of the software, allowing users to modify or remove the shell allow list as needed. Users should monitor the project for any future updates or patches and consider restricting local access to trusted users only.
