CVE-2026-55600: Part-DB stored HTML injection in BOM validation via Part name

CVE-2026-55600 · Severity: info · Published 2026-10-23

Part-DB is an open-source inventory management system for electronics components used by engineers and technicians to track parts and bill of materials. A user with permission to edit Part names can inject malicious HTML (such as fake login links or forms) that will be displayed to other users when they import a bill of materials file. While JavaScript execution is blocked, the injected HTML could enable phishing attacks or credential harvesting from trusted users viewing validation messages.

Technologies: Part-DB. Vendors: Part-DB.

How to fix

  • Fixed in: 2.12.2

Restrict Part edit permissions to trusted administrative users, or limit BOM import privileges to non-admin users until the update can be applied.

Technical details

The vulnerability is a stored HTML injection in BOM validation results caused by Twig's |raw filter rendering unescaped Part names. An authenticated user with Part edit permissions can store HTML markup in a Part name field; when another user imports a BOM CSV referencing that Part ID, the malicious Part name is rendered as HTML in the BOM validation page. Attack requires two users with at minimum Editor permissions, and an attacker can inject arbitrary HTML elements (links, forms, images, CSS-based UI elements) though inline JavaScript is blocked by CSP.
