What is CVE-2026-31894?

WeGIA, a web management tool designed for charitable institutions, contains a vulnerability in version 3.6.5 where the loadBackupDB() function extracts tar.gz archives into a temporary directory using PHP's PharData class. The method lacks sufficient validation on extracted archive members, particularly for symbolic links. This oversight allows for potential directory traversal attacks, which could lead to unauthorized access to sensitive files. The issue was resolved in version 3.6.6, ensuring that both extraction and file reading processes validate the integrity of archive contents.
