CVE-2026-69098
9.8 CRITICALpublic exploit availablePublished 2026-08-04 · Updated 2026-08-05
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.
