Lifecycle Timeline
3DescriptionCVE.org
A vulnerability was determined in AstrBotDevs AstrBot 4.23.6. Affected by this issue is the function _normalize_rw_path of the file astrbot/core/tools/computer_tools/fs.py. This manipulation causes incorrect authorization. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Incorrect authorization in AstrBot 4.23.6 allows remote low-privileged attackers to bypass filesystem path restrictions via the _normalize_rw_path function in astrbot/core/tools/computer_tools/fs.py, resulting in unauthorized read, write, or access to files outside the intended scope. The vulnerability stems from improper path normalization logic that fails to enforce access controls correctly, enabling authenticated users to escape sandboxed file boundaries. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged user account on the AstrBot instance (CVSS PR:L) - unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L reflects a network-exploitable, low-complexity vulnerability requiring only low-privilege authentication. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low-privileged account on an internet-exposed AstrBot instance crafts a malicious file path payload that exploits the flawed `_normalize_rw_path` normalization logic - for example, using path traversal sequences that survive normalization and bypass authorization checks - to read, write, or enumerate files outside the permitted filesystem scope. Because a public proof-of-concept is available on GitHub, exploitation does not require advanced reverse engineering. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the vendor did not respond to coordinated disclosure, and no fixed version is referenced in available sources. … Detailed patch versions, workarounds, and compensating controls in full report. |
