WordPress 2.1.3 Akismet Vulnerability

Updates:
14/05/07 Added link to new version

David Kierznowski of Operation n has discovered a serious flaw in the Akismet anti-spam plugin that comes by default with the latest version of WordPress (2.1.3).

It has not been confirmed as yet, but I believe this will affect all versions of the plugin. The vendor has been notified, and more information regarding the vulnerability will be released when a suitable fix has been released.

I know its painful, but its recommended that you disable the Akismet plugin immediately.

The vendor was notified: 14/05/07
Response received: 14/05/07
Fix received: 14/05/07

The Akismet v2.0.2 Download upgrade has been made to address these issues and may be downloaded here.

    I don’t know if this fix is completely correct. When I want to go to the aksimet-admin page from the dashboard the link is:
    http://edit-comments.php/?page=akismet-admin
    without the proper URL.
    I de-activated the plugin first and then replaced the old akismet.php with the new one. You seem to have contact with the developers, so I thought I should put the remark here. Other than that it is good to see such a fast response.

    Jan, workaround:
    Edit your Akismet plugin, search for “$link?page=akismet-admin” and remove the function around it, its is something like clean_link(”$link?page=akismet-admin”) -> “$link?page=akismet-admin” and now it works again.
    They should test their Plugins before release imo ;)

    cheers beNi
