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 extractCondFmtCellIs and also indexes ColorScale.Cfvo, DataBar.Cfvo, and DataBar.Color without complete structural checks. When a crafted worksheet supplies a cellIs, dataBar, or colorScale rule missing expected children and the application calls GetConditionalFormats, missing formula, color, value-object, or colorScale data reaches an out-of-range index or nil dereference, allowing an attacker to panic and terminate an unprotected process. No fixed version is available as of this review.
