This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from excelize. Update excelize to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
