- Cross-Site Scripting (XSS) – Unsanitized user input in themes or plugins.
- Local File Inclusion (LFI) – Improper path filtering allowing access to system files.
- SQL Injection – If the alpha uses a database (Pico typically uses flat files, but plugins might add DB layers).
- Authentication Bypass – Session handling flaws in new login systems.
- PHP Object Injection – If unserialization of user-supplied data occurs.
Long-term Strategy:
- Never expose alpha/beta software to the public internet. Use
localhost or VPN-restricted staging environments.
- Implement File Integrity Monitoring (FIM) for
plugins/ and themes/ directories.
- Run the web server with
disable_functions = system, exec, shell_exec, passthru, popen in php.ini.
