{"schema":"threatline.record/2","record":{"id":"CVE-2026-86020","aliases":["GHSA-hxw4-frfg-f8jw"],"summary":"Part-DB: Spreadsheet Formula Injection in XLSX Part Exports","details":"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.","categories":["Unclassified"],"product":"Part-DB-server","vendor":"Part-DB","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-86020","source_modified_at":"2026-10-23T14:59:59.159Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Part-DB-server","vendor":"Part-DB","versions":[{"version":"< 2.13.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":4.6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00119,"percentile":0.01681,"score_date":"2026-10-23"},"published_at":"2026-10-23T04:05:24.420Z","modified_at":"2026-10-23T14:59:59.159Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-86020","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T14:59:59.159Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-86020","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-hxw4-frfg-f8jw","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-23T14:48:41.603210Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T14:59:59.159Z","content_hash":"c92d85de41ae6dc84aff4f051b4ad8f23d197c61bd1e0965cd8c2cafbbbb4603"}}
