CVE-2026-10211 · Severity: medium · CVSS 6.3 · Published 2026-06-01

AstrBot, a chatbot and automation framework, contains a security flaw that allows non-administrator users to write or edit files they should not have access to. By exploiting a mismatch in how the system checks file permissions, an attacker can inject malicious code into the bot's shared skills directory. This could lead to a complete takeover of the bot's functions or the underlying server when those malicious skills are executed.

## Technical details

An authorization bypass exists in AstrBot's filesystem tools due to a logic error in the `_normalize_rw_path` function within `astrbot/core/tools/computer_tools/fs.py`. The application incorrectly reuses `_read_allowed_roots` (which includes global skill directories) to validate write and edit operations for restricted users. By providing an absolute path to the `FileWriteTool` or `FileEditTool`, a remote authenticated attacker with low privileges can bypass intended workspace restrictions. This allows the attacker to write arbitrary files into the `data/skills` directory, potentially leading to persistent malicious skill injection and remote code execution (RCE) when the injected skills are loaded. As of the advisory date, no official patch has been released.
