Summary
In princezuda SafestClaw up to version 4.2.4, a vulnerability was found in the ShellAction._validate_command function in src/safestclaw/actions/shell.py. Manipulation leads to an incomplete blacklist, allowing local bypass of security controls.
Risk Assessment
A local attacker can bypass shell restrictions and execute unauthorized commands, potentially leading to privilege escalation or system integrity compromise.
Recommendation
Manually review and modify the allowed command list in SafestClaw configuration, and monitor for publicly available exploits.

Original NVD description (English source)
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."
