FrankenPHP vulnerabilities

FrankenPHP is a modern application server for PHP. Prior to 1.12.5, the official FrankenPHP Debian and Alpine Docker images include a default /app/public/index.php that executes phpinfo(). A derived image that does not overwrite this placeholder serves the diagnostics page in production and can disclose environment variables used for secrets, PHP configuration directives, loaded extensions, software versions, and system paths. Images built using the documented pattern with their own /app/public/index.php are not affected, and already derived images must be rebuilt or supplied with an application index to remove the exposed placeholder. This issue is fixed in version 1.12.5.

FrankenPHP is a modern application server for PHP. Prior to 1.12.5, in worker mode, when the session extension is loaded as a shared module, PHP session state can be retained between requests, leading to cross-user session exposure and possible session hijacking.

FrankenPHP is a modern application server for PHP, which in versions from 1.11.2 to before 1.12.3 has an issue in the splitPos() function in cgi.go. This flaw allows an attacker to mislead the server into treating a non-PHP file as a PHP script, potentially leading to remote code execution.
