CVE-2024-45048 [MEDIUM] Loft Data Grids - Moderately critical - Multiple vulnerabilities - SA-CONTRIB-2024-054
Title: Loft Data Grids - Moderately critical - Multiple vulnerabilities - SA-CONTRIB-2024-054
Vulnerability Type: Multiple vulnerabilities
Description: This module provides serialization formats for use by other modules. The module includes a version of phpoffice/phpspreadsheet which has multiple known security vulnerabilities.
Solution: If you use the Loft Data Grids module for Drupal 7.x, install one of: Loft Data Grids 7.x-2.7 - which removes support for the XLSX format, as the patched version requires PHP 8. Loft Data Grids 7.x-3.0 - which includes XLSX support, by requiring PHP 8 and Composer installation. See the module's README-file for more information.
