SCA: security update for phpoffice/phpspreadsheet (GHSA-7c6m-4442-2x6m)

high Tenable Self-Hosted Container Security Plugin ID 441012

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. Prior to 1.30.4, 2.1.16,
 2.4.5, 3.10.5, and 5.7.0, the XLSX reader's ColumnAndRowAttributes::readRowAttributes() method reads row
 numbers from XML attributes without validating them against the spreadsheet maximum row limit
 (AddressRange::MAX_ROW = 1,048,576). An attacker can craft a minimal XLSX file (~1.6KB) containing a <row
 r="999999999"/> element that inflates cachedHighestRow to 999,999,999, causing any subsequent row
 iteration to attempt ~1 billion loop cycles and exhaust CPU resources. This vulnerability is fixed in
 1.30.4, 2.1.16, 2.4.5, 3.10.5, and 5.7.0. (CVE-2026-40902)

Solution

Update the phpoffice/phpspreadsheet library and its related packages to version 1.30.4 or later.
