{"id":"CVE-2026-107211","summary":"Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic","details":"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.","aliases":["GHSA-mx22-3794-2vpv"],"modified":"2026-10-09T02:49:20.514564928Z","published":"2026-10-07T17:11:17.902Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-129"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107211.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107211.json"},{"type":"ADVISORY","url":"https://github.com/qax-os/excelize/security/advisories/GHSA-mx22-3794-2vpv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107211"},{"type":"FIX","url":"https://github.com/qax-os/excelize/commit/6258dcebc4e2a2aed985c38a08098dfd908521d1"},{"type":"FIX","url":"https://github.com/qax-os/excelize/pull/2435"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/qax-os/excelize","events":[{"introduced":"688808b2b4f7bb1f338991c810cd2ee6a7bb1451"},{"fixed":"6258dcebc4e2a2aed985c38a08098dfd908521d1"}],"database_specific":{"extracted_events":[{"introduced":"2.8.1"},{"last_affected":"2.11.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v2.11.0","v2.10.1","v2.10.0","v2.9.1","v2.9.0","v2.8.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107211.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
