What is CVE-2026-86019?

CVE-2026-86019 is a medium-severity vulnerability in Part-DB-server, published on 23 Oct 2026.

Official description

Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB allows authenticated API users to bypass the configured maximum attachment file size by uploading attachments through the API using base64-encoded file data. The application enforces the configured attachment size limit for normal browser-based file uploads, but the API base64 upload path does not apply the same size validation. As a result, an authenticated user with API access and permission to create attachments can upload files larger than the configured maximum attachment size, potentially exhausting disk space and causing a denial of service. This issue has been patched in version 2.13.2.

Weakness: CWE-770, CWE-400
