CVE-2026-69098

kotaemon 0.12.0 Unauthenticated Remote Code Execution via Insecure Deserialization

kotaemon through 0.12.0 contains an insecure deserialization vulnerability in the checkconnection 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.checkoutput and arbitrary arguments, achieving remote code execution with application process privileges.
