Name of the Vulnerable Software and Affected Versions Joomla! versions prior to 3.9.3

Description An issue was discovered where the phar:// stream wrapper can be used for object injection attacks due to the lack of a protection mechanism. This allows the phar:// handler to be used for non .phar-files, potentially leading to exploitation.

Recommendations For versions prior to 3.9.3, update to version 3.9.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the phar:// stream wrapper to minimize the risk of object injection attacks.
