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.
