Path Traversal in Cinnamon Kotaemon
CVE-2025-53358
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.
