{"id":"CVE-2026-86020","state":"PUBLISHED","title":"Part-DB: Spreadsheet Formula Injection in XLSX Part Exports","description":"Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB contains a spreadsheet formula injection vulnerability in the part import/export workflow. An authenticated user with permission to import parts can import a CSV file containing formula-prefixed values, such as =1+1, into user-controlled part fields. When the affected part is later exported as an XLSX spreadsheet, Part-DB writes the attacker-controlled value using PhpSpreadsheet's setCellValue() method without neutralising spreadsheet formula characters. As a result, the exported XLSX file contains an executable spreadsheet formula cell rather than a plain text value. If another user exports and opens the spreadsheet, the formula may be evaluated by their spreadsheet software. This issue has been patched in version 2.13.2.","publishedAt":"2026-10-23T04:05:24.420Z","updatedAt":"2026-10-23T14:59:59.159Z","severity":{"score":4.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Part-DB Part-DB-server"],"affected":[{"vendor":"Part-DB","product":"Part-DB-server","versions":[{"version":"< 2.13.2","status":"affected"}]}],"references":["https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-hxw4-frfg-f8jw","https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.2"],"weaknesses":["CWE-20","CWE-1236"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/86xxx/CVE-2026-86020.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-86020","state":"PUBLISHED","datePublished":"2026-10-23T04:05:24.420Z","dateUpdated":"2026-10-23T14:59:59.159Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-04T19:23:40.691Z"},"containers":{"cna":{"title":"Part-DB: Spreadsheet Formula Injection in XLSX Part Exports","descriptions":[{"lang":"en","value":"Part-DB is an open source inventory management system for electronic components.
