CVE-2025-63914 (GCVE-0-2025-63914)
Vulnerability from cvelistv5 – Published: 2025-11-24 00:00 – Updated: 2025-11-24 19:29
VLAI
Summary
An issue was discovered in Cinnamon kotaemon 0.11.0. The _may_extract_zip function in the \libs\ktem\ktem\index\file\ui.py file does not check the contents of uploaded ZIP files. Although the contents are extracted into a temporary folder that is cleared before each extraction, successfully uploading a ZIP bomb could still cause the server to consume excessive resources during decompression. Moreover, if no further files are uploaded afterward, the extracted data could occupy disk space and potentially render the system unavailable. Anyone with permission to upload files can carry out this attack.

CVE-2025-53358 (GCVE-0-2025-53358)
Vulnerability from cvelistv5 – Published: 2025-07-02 15:38 – Updated: 2025-07-02 16:00

Title
kotaemon Vulnerable to Path Traversal via Link Upload
Summary
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.

Summary
An issue was discovered in Cinnamon kotaemon 0.11.0. The _may_extract_zip function in the \libs\ktem\ktem\index\file\ui.py file does not check the contents of uploaded ZIP files. Although the contents are extracted into a temporary folder that is cleared before each extraction, successfully uploading a ZIP bomb could still cause the server to consume excessive resources during decompression. Moreover, if no further files are uploaded afterward, the extracted data could occupy disk space and potentially render the system unavailable. Anyone with permission to upload files can carry out this attack.

CVE-2025-53358 (GCVE-0-2025-53358)
Vulnerability from nvd – Published: 2025-07-02 15:38 – Updated: 2025-07-02 16:00

Title
kotaemon Vulnerable to Path Traversal via Link Upload
Summary
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.
Severity
6.5 (Medium)
