CVE-2025-53927 | BDVDB-2026-286586 Detail

1Panel-devMaxKB

Description#

MaxKB is an open-source AI assistant for enterprise. Prior to version 2.0.0, the sandbox design rules can be bypassed because MaxKB only restricts the execution permissions of files in a specific directory. Therefore, an attacker can use the `shutil.copy2` method in Python to copy the command they want to execute to the executable directory. This bypasses directory restrictions and reverse shell. Version 2.0.0 fixes the issue.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact low. Attack vector: network.

Weaknesses#

CWE-94 Improper Control of Generation of Code ('Code Injection')
