Short explanation
Part-DB versions prior to 2.12.2 are vulnerable to stored HTML injection because BOM validation pages render Part names without escaping. An attacker who can edit a Part name can store HTML markup; when another user imports a BOM CSV referencing that Part ID, the malicious HTML is rendered in the validation result page. The CSP blocks script execution, but links, forms, images and CSS can still be injected.
This enables attackers to embed malicious content in trusted pages, potentially deceiving users and leaking data.
What should be done?
- Upgrade Part-DB to version 2.12.2 or later
- Escape or sanitize Part name inputs
- Strengthen the Content Security Policy
- Audit the database for suspicious Part names
- Monitor vendor security advisories
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
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.
