DescriptionGitHub Advisory

WeGIA is a web manager for charitable institutions. In 3.6.5, The patched loadBackupDB() extracts tar.gz archives to a temporary directory using PHP's PharData class, then uses glob() and file_get_contents() to read SQL files from the extracted contents. Neither the extraction nor the file reading validates whether archive members are symbolic links. This vulnerability is fixed in 3.6.6.

When processing tar.gz archives, the application fails to validate whether extracted members are symbolic links before reading their contents, enabling an attacker to access sensitive files like database credentials or configuration data. No patch is currently available for this vulnerability.
