A vulnerability was found in AstrBotDevs AstrBot up to 4.25.5. Impacted is the function _normalize_rw_path of the file astrbot/core/tools/computer_tools/fs.py of the component Filesystem Computer-Use Tool. Performing a manipulation results in link following. The attack is only possible with local access. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
CVE-2026-16077 is a vulnerability in AstrBotDevs AstrBot versions 4.25.0 through 4.25.5 affecting the _normalize_rw_path function in the filesystem computer-use tool component (astrbot/core/tools/computer_tools/fs.py). The vulnerability allows an attacker with local access and low privileges to manipulate the function to perform link following, potentially leading to unauthorized filesystem access or modification. The vulnerability has a CVSS 4.8 (medium) score, indicating limited impact and exploitability. The vendor was contacted but did not respond, and no patch or remediation guidance is currently available.
Potential Impact
An attacker with local access and low privileges can exploit this vulnerability to perform link following via the _normalize_rw_path function. This could allow unauthorized access or modification of filesystem paths that the application interacts with. The impact is limited by the requirement for local access and low privileges, and no user interaction is needed. There is no evidence of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no official fix is available, users should restrict local access to trusted users only and monitor for suspicious activity related to filesystem operations. Avoid running AstrBot with unnecessary privileges until a fix is released.
