## Summary

Part-DB, an open source electronics inventory management system, is affected by a stored HTML injection flaw in its BOM import validation pages. A user who can edit a part name can insert HTML that is displayed unescaped to other users who import a BOM referencing that part, allowing malicious links, forms, or visual elements to appear within a trusted Part-DB page.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Part-DB Part-DB-server: fixed in 2.12.2

## 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.
