Summary

Kotaemon through 0.12.0 fails to properly validate conversation ownership in select_conv, delete_conv, rename_conv, and on_set_public_conversation functions in control.py. Attackers can read other users' chat histories, delete conversations, or rename conversations by supplying arbitrary conversation identifiers without proper authorization checks.

Risk Assessment

The risk includes user privacy breach, unauthorized data deletion, and conversation manipulation, potentially leading to data loss and trust erosion.

Recommendation

Update Kotaemon to a patched version and implement ownership-based access controls. Also conduct a code audit for similar vulnerabilities.

Other vulnerabilities in Kotaemon

CVE-2026-69098Critical
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.
