SCA: security update for phpoffice/phpspreadsheet (GHSA-2mrg-gjxq-2gvr)

high Tenable Self-Hosted Container Security Plugin ID 445215

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. In versions 4.0.0 through
 5.8.0, 3.3.0 through 3.10.6, 2.2.0 through 2.4.6, 2.0.0 through 2.1.17, and all releases up to and
 including 1.30.5, the Gnumeric reader reads attacker-supplied .gnumeric files into memory and, when the
 file starts with gzip magic bytes, calls gzdecode() on the full compressed contents without enforcing a
 decompressed-size limit. A very small compressed .gnumeric file can expand to data larger than the PHP
 memory limit and crash the process during Gnumeric::canRead() before the file is rejected or fully parsed.
 This is reachable through normal file-type detection and Gnumeric loading paths, so applications that
 accept attacker-controlled spreadsheet uploads can suffer denial of service. This issue has been fixed in
 versions 5.8.1, 3.10.7, 2.4.7, 2.1.18 and 1.30.6. (CVE-2026-59932)

Solution

Update the phpoffice/phpspreadsheet library and its related packages to version 1.30.6 or later.
