Go to dashboardThe Excelize Go library panics on malformed encrypted OLE/CFB Excel workbooks when they are opened or passed to its Decrypt function, instead of returning an error. An attacker who supplies such a file can crash the process that calls the library.

Run go list -m github.com/xuri/excelize/v2 in each Go module and check whether the version falls between 2.3.1 and 2.11.0.
Also check for the older module path github.com/360EntSecGroup-Skylar/excelize/v2 from 2.3.1 onward.
2.11.1-0.20260915055537-22f76f9acb94 or later, per the govuln fixed-version dataEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.3.1 to 2.11.0, the decryption dispatch performs insufficient structural and parameter validation before standard and agile decryptors slice, index, allocate, and divide using attacker-controlled values. Decrypt passes attacker-controlled EncryptionInfo and EncryptedPackage data into standardDecrypt or agileDecrypt before validating the structures used by those routines. When a malformed OLE compound file with a version-valid EncryptionInfo stream is opened or passed to Decrypt, nine malformed-input classes reach unrecovered Go runtime panics instead of the documented error path, allowing an attacker to terminate the calling process. No fixed version is available as of this review.
