CVE-2026-107224

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, a Zip64 uncompressed size with the high bit set is converted from uint64 to a negative int64 before signed size-limit checks and allocation. ReadZipReader obtains UncompressedSize64 throu...

CVE-2026-107222

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-2026-107224

The Excelize Go library (versions 2.1.0 to 2.11.0 ) is vulnerable to a panic during workbook opening due to an integer overflow/wraparound . When a crafted Zip64 entry declares an uncompressed size between $2^{63}$ and $2^{64}-1$, the library converts the uint64 value into a negative int64. This ...

CVE-2026-107223 Excelize: Unbounded <col max> attribute is loaded with no MaxColumns check and expanded per-column by flatCols(), so any column mutator hangs or OOMs the process

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, flatCols expands file-loaded column ranges without validating Min and Max against the worksheet column limit. SetColWidth reaches flatCols, which expands xlsxCol.Min through xlsxCol.Max...

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-2026-107220 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.
