CVE-2025-53358

The pipeline streams these paths directly and stores them, enabling attackers to traverse directories (e.g. ../../../../../.env) and exfiltrate sensitive files.

MEDIUM 6.5EPSS 0.46%

Does this matter?

Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.

Description

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.
