Some words (curl, wget) cause errors (403 Forbidden) in post.php

[Hal_Canary]

How to reproduce:

1) go to wordpress/wp-admin/post.php to create a new post.

2) Enter the phrase "How do I curl hair with a curling iron?" into the post textbox thing.

3) Hit "save".

Result:

I get a 403 Forbidden error.

The phrase "wget is a non-interactive network downloader." also causes a problem.

Wordpress verion: 2.0.4

MySQL version: 4.0.27-standard

PHP version: 4.4.4

Sounds like either a bad host setting or mod_security. Ask your hosting provider if there's anything in their security setup that would block such.

WordPress shouldn't be blocking any of this, as it doesn't make system() calls on the_content(). Also take a look at your plugin list - perhaps PHPExec or runPHP is being enabled and trying to execute curl() or wget() functions in php...?

Talk to your host about mod_security. This has been discussed many times on the support forums.
