CVE-2026-16129

Full vulnerability record from the local CVENow database.

Description

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."

La presencia de esta vulnerabilidad permanece incierta en este momento. El mantenedor del proyecto explica: ’Sobre el papel tienes razón, esto es una vulnerabilidad. En la práctica, nada de lo que tu IA generó muestra cómo hace vulnerables a los usuarios. Es de código abierto. Alguien puede modificar la lista de permitidos del shell o eliminar ese sistema.
