CVE-2026-107222

The Excelize Go library, used for reading and writing Microsoft Excel spreadsheets, is vulnerable in versions 2.7.0 to 2.11.0 . The GetConditionalFormats function fails to perform sufficient length or nil checks when extracting conditional-formatting rules. Specifically, it indexes required child...

CVE-2026-107222 Excelize: GetConditionalFormats indexes conditional-formatting rule sub-elements with no length or nil check

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.7.0 to 2.11.0, conditional-format extraction indexes required child slices or dereferences an optional colorScale child without validating malformed rule structure. GetConditionalFormats reaches...

CVE-2026-107221 Excelize: a row whose earlier cell has a higher column reference than its last cell panics index out of range on almost every worksheet read API

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.0.0 to 2.11.0, checkRow sizes its target cell slice from the last cell in XML document order and then re-scatters every cell by its explicit column reference. GetCellValue reaches workSheetReader and...

CVE-2026-107221

The Excelize Go library (versions 2.0.0 to 2.11.0 ) is vulnerable to an out-of-bounds write (CWE-787) during non-streaming worksheet read operations. The root cause lies in the checkRow function, which incorrectly sizes a target cell slice based on the last cell in XML document order. If a crafte...

CVE-2026-107220 Excelize: Panic in cellInRange on a worksheet with an empty mergeCell ref

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.7.1 to 2.11.0, mergeCellsParser leaves the cached rectangle empty for an empty mergeCell ref and then passes that empty slice to cellInRange without a length check. GetCellValue reaches mergeCellsParser...

CVE-2026-107220

The Excelize Go language library (versions 2.7.1 to 2.11.0 ) contains a vulnerability where the mergeCellsParser fails to perform a length check when handling an empty mergeCell ref . Specifically, it passes an empty slice to cellInRange , which is then accessed by GetCellValue . An attacker can ...
