Technical details

The vulnerability exists in the migrateAddonConfig() function, which includes and executes config.php files from addon ZIP archives without validation. An authenticated attacker with admin privileges can supply a crafted ZIP file containing malicious PHP code in config.php to achieve remote code execution under the web server process. The fix replaces the include statement with static analysis using token_get_all(), preventing code execution while still parsing configuration.
