CVE-2025-67506

PipesHub Vulnerable to Path Traversal through Unauthenticated Arbitrary File Upload

State: Published
Severity: 9.8 Critical
Published: Dec 10, 2025
Updated: Dec 10, 2025
Reserved: Dec 8, 2025

Description

PipesHub is a fully extensible workplace AI platform for enterprise search and workflow automation. Versions prior to 0.1.0-beta expose POST /api/v1/record/buffer/convert through missing authentication. The endpoint accepts a file upload and converts it to PDF via LibreOffice by uploading payload to os.path.join(tmpdir, file.filename) without normalizing the filename. An attacker can submit a crafted filename containing ../ sequences to write arbitrary files anywhere the service account has permission, enabling remote file overwrite or planting malicious code. This issue is fixed in version 0.1.0-beta.
