AI risk analysis

Summary
The flaw allows unauthenticated attackers to execute arbitrary code by exploiting an insecure deserialization vulnerability in the check_connection endpoint, leading to remote code execution with application process privileges.
Exploitability
Exploitation is relatively straightforward given the unauthenticated nature and the ability to override the __type__ field with subprocess.check_output, requiring only crafted YAML/JSON input.
Blast radius
If exploited, the impact could be severe, as it allows for remote code execution with the privileges of the application process, potentially leading to full system compromise.
Detection
No reliable host or network indicator is derivable from the published description.
Prioritized remediation
Upgrade to version 0.12.1 or later.

NVD description

kotaemon through 0.12.0 contains an insecure deserialization vulnerability in the check_connection endpoint that allows unauthenticated attackers to instantiate arbitrary Python classes by supplying crafted YAML/JSON input with a __type__ field. Attackers can exploit this to override the __type__ field with subprocess.check_output and arbitrary arguments, achieving remote code execution with application process privileges.
