CVE-2026-86020 Details
Description
Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB contains a spreadsheet formula injection vulnerability in the part import/export workflow. An authenticated user with permission to import parts can import a CSV file containing formula-prefixed values, such as =1+1, into user-controlled part fields. When the affected part is later exported as an XLSX spreadsheet, Part-DB writes the attacker-controlled value using PhpSpreadsheet's setCellValue() method without neutralising spreadsheet formula characters. As a result, the exported XLSX file contains an executable spreadsheet formula cell rather than a plain text value. If another user exports and opens the spreadsheet, the formula may be evaluated by their spreadsheet software. This issue has been patched in version 2.13.2.
A spreadsheet formula injection vulnerability has been identified in Part-DB, an open-source inventory management system for electronic components, prior to version 2.13.2. The vulnerability arises in the part import/export workflow, where an authenticated user with permission to import parts can upload a CSV file containing formula-prefixed values into user-controlled part fields. When the part is later exported as an XLSX file, Part-DB uses PhpSpreadsheet's setCellValue() method to write the imported value without removing spreadsheet formula characters. This oversight allows the exported file to contain an executable formula instead of a plain text value. If another user opens the spreadsheet, the formula may be evaluated by their spreadsheet software.
Users can update to Part-DB version 2.13.2 or later, where this vulnerability has been patched.
