SCA: security update for phpoffice/phpspreadsheet (GHSA-3x94-m842-937c)

high Tenable Cloud Security Plugin ID 477602

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 1.30.7, 2.1.19,
 2.4.8, 3.10.8, and 5.10.0, XmlScanner::scan in src/PhpSpreadsheet/Reader/Security/XmlScanner.php uses a
 DOCTYPE detection pattern that accounts for NUL-byte interleaving but not ISO-2022 escape sequences in
 XLSX XML parts. The escape sequences prevent the scanner from matching the declaration, and XML charset
 normalization then removes the escape bytes before parsing, exposing a valid DOCTYPE and entity
 definitions. Processing an attacker-controlled XLSX can therefore cause entity-expansion denial of service
 on supported PHP versions and can permit local file access or SSRF on PHP before 8.0 or when LIBXML_NOENT
 is enabled. This issue is fixed in versions 1.30.7, 2.1.19, 2.4.8, 3.10.8, and 5.10.0. (CVE-2026-108358)

Solution

Update the phpoffice/phpspreadsheet library and its related packages to version 1.30.7 or later.
