SCA: security update for phpoffice/phpspreadsheet (GHSA-q4q6-r8wh-5cgh)

critical Tenable Cloud Security Plugin ID 441013

Description

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

 - PhpSpreadsheet is a library for reading and writing spreadsheet files. In versions 1.30.2 and earlier,
 2.0.0 through 2.1.14, 2.2.0 through 2.4.3, 3.3.0 through 3.10.3, and 4.0.0 through 5.5.0, when the
 filename argument to IOFactory::load() is user-controlled, an attacker can supply a PHP stream wrapper
 path (such as phar://, ftp://, or ssh2.sftp://) that passes the is_file() check in File::assertFile(). The
 phar:// wrapper triggers deserialization of the PHAR metadata, which can lead to remote code execution if
 a suitable gadget chain is available in the application. The ftp:// and ssh2.sftp:// wrappers can be used
 for server-side request forgery. This issue has been fixed in versions 1.30.3, 2.1.15, 2.4.4, 3.10.4, and
 5.6.0. (CVE-2026-34084)

Solution

Update the phpoffice/phpspreadsheet library and its related packages to version 1.30.3 or later.
