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.\n\n## Affected\n\n- `excelize >= 2.8.1, <= 2.11.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-107211)\n\nAffected packages:\n\n- `github.com/xuri/excelize/v2 >= 2.8.1, < 2.11.1-0.20261003002531-6258dcebc4e2`\n\nPatched in:\n\n- `github.com/xuri/excelize/v2 2.11.1-0.20261003002531-6258dcebc4e2`\n\nSource: https://github.com/advisories/GHSA-mx22-3794-2vpv","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":219698,"id":"CVE-2026-107211","ts":1791901782008,"field":"cvss","old":"8.7","new":"5.5"},{"seq":219697,"id":"CVE-2026-107211","ts":1791901782008,"field":"severity","old":"high","new":"medium"}]}
