Description Josh Bressers 2008-11-18 01:47:16 UTC

WordPress 2.6.3 relies on the REQUEST superglobal array in certain
dangerous situations, which makes it easier for remote attackers to
conduct delayed and persistent cross-site request forgery (CSRF)
attacks via crafted cookies, as demonstrated by attacks that (1)
delete user accounts or (2) cause a denial of service (loss of
application access). NOTE: this issue relies on the presence of an
independent vulnerability that allows cookie injection.

2.6.5 is available which seems to fix the security vulnerability

http://wordpress.org/development/2008/11/wordpress-265/

They do not mention the CVE number as far as I see it but the changes to feed.php
seems to change the behaviour concerning the REQUEST variable:

http://trac.wordpress.org/changeset?old_path=tags%2F2.6.3&old=&new_path=tags%2F2.6.5&new=#file2

I will push updates for wordpress.

From this quick look at the 2.6.3 -> 2.6.5 changeset, I fail to see any change that may be possibly related to this issue.  $_REQUEST still seems widely used in 2.6.5, feed.php is unlikely to be the only place to be affected.  Please do not mention this bug/CVE in the 2.6.5 update request.

According to http://codex.wordpress.org/CVEs#2008 this only affected 2.6.3.
