{"id":"CVE-2026-107211","state":"PUBLISHED","title":"Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, separately parsed pivot-table field indices are used to index the pivot-cache field-name slice without bounds checks. extractPivotTableFields uses getPivotCacheFieldsName output while processing GetPivotTables and trusts the dataField fld attribute as an index. When a crafted workbook supplies a pivot-field count mismatch or an out-of-range dataField fld value before GetPivotTables is called, the unchecked index causes a Go slice-bounds panic that escapes the library, allowing an attacker to crash the process or request worker. No fixed version is available as of this review.","publishedAt":"2026-10-07T17:11:17.902Z","updatedAt":"2026-10-07T19:03:18.640Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["qax-os excelize"],"affected":[{"vendor":"qax-os","product":"excelize","versions":[{"version":">= 2.8.1, <= 2.11.0","status":"affected"}]}],"references":["https://github.com/qax-os/excelize/security/advisories/GHSA-mx22-3794-2vpv","https://github.com/qax-os/excelize/pull/2435","https://github.com/qax-os/excelize/commit/6258dcebc4e2a2aed985c38a08098dfd908521d1"],"weaknesses":["CWE-129"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/107xxx/CVE-2026-107211.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-107211","state":"PUBLISHED","datePublished":"2026-10-07T17:11:17.902Z","dateUpdated":"2026-10-07T19:03:18.640Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-07T14:34:14.815Z"},"containers":{"cna":{"title":"Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic","descriptions":[{"lang":"en","value":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets.
