Summary

A vulnerability in PHPSpreadsheet allows attackers to create crafted XLSX files that link media from external URLs. When users open these files, the library attempts to retrieve image size by accessing the provided URLs. By manipulating php://filter URLs, an attacker can expose sensitive information from any file on the server, including AWS IAM credentials. It is crucial for all users of PHPSpreadsheet to upgrade to versions 1.29.2, 2.1.1, or 2.3.0, as there are currently no known workarounds for this security issue.

Affected Version(s)

PhpSpreadsheet < 1.29.2 < 1.29.2

PhpSpreadsheet >= 2.0.0, < 2.1.1 < 2.0.0, 2.1.1

PhpSpreadsheet >= 2.2.0, < 2.3.0 < 2.2.0, 2.3.0
