CVE-2026-55600

Part-DB: Stored HTML injection in BOM validation results via unescaped Part name

Published Oct 23, 2026 CVSS 4.0 · 5.7 Medium EPSS < 1% KEV · Not listed
Description
Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.2, Part-DB renders BOM validation information messages using Twig's |raw filter. These messages include translated placeholders populated with user-controlled Part names. A user who can edit a Part name can store HTML markup in the Part name. When another user imports a BOM CSV referencing that Part ID, the malicious Part name is rendered as HTML in the victim's BOM validation result page. This results in a cross-user stored HTML injection issue. JavaScript execution appears to be blocked by the current Content Security Policy, but arbitrary HTML links, forms, images, and CSS-based UI elements can still be injected into a trusted Part-DB page. This issue has been patched in version 2.12.2.
