CVE-2025-53358: Cinnamon Kotaemon

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

kotaemon is an open-source RAG-based tool for document comprehension. From versions 0.10.6 and prior, in libs/ktem/ktem/index/file/ui.py, the index_fn method accepts both URLs and local file paths without validation. The pipeline streams these paths directly and stores them, enabling attackers to traverse directories (e.g. ../../../../../.env) and exfiltrate sensitive files. This issue has been patched via commit 37cdc28, in version 0.10.7 which has not been made public at time of publication.

Affected products

• Cinnamon Kotaemon: up to and including 0.10.6
