{"id":"CVE-2026-55600","state":"PUBLISHED","title":"Part-DB: Stored HTML injection in BOM validation results via unescaped Part name","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.","publishedAt":"2026-10-23T03:55:48.661Z","updatedAt":"2026-10-30T16:30:57.428Z","severity":{"score":5.7,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Part-DB Part-DB-server"],"affected":[{"vendor":"Part-DB","product":"Part-DB-server","versions":[{"version":"< 2.12.2","status":"affected"}]}],"references":["https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-qqrh-jjhg-vv5r","https://github.com/Part-DB/Part-DB-server/releases/tag/v2.12.2"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-30T16:34:06.595Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/55xxx/CVE-2026-55600.json","commit":"9e54b3557627dfb3a1074c39eb8411c2987ff251","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-55600","state":"PUBLISHED","datePublished":"2026-10-23T03:55:48.661Z","dateUpdated":"2026-10-30T16:30:57.428Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-16T23:18:03.170Z"},"containers":{"cna":{"title":"Part-DB: Stored HTML injection in BOM validation results via unescaped Part name","descriptions":[{"lang":"en","value":"Part-DB is an open source inventory management system for electronic components.
