#11938 closed defect (bug) (wontfix)

Akismet doesn't take the HTTP_X_FORWARDED_HOST into account, sees all comments as spam

Reported by: husky's profile husky Owned by:
Milestone: Priority: normal
Severity: normal Version: 2.9.1
Component: General Keywords: close has-patch
Focuses: Cc:


On some installations, requests are forwarded to separate 'PHP workers' and the original REMOTE_ADDR key in the $_SERVER superglobal might be changed to the forwarders IP instead of the original commenter. This means that all requests have the same REMOTE_ADDR when send to the Akismet servers and therefore are all seen as spam.

The forwarding servers add an extra header to the HTTP request called 'HTTP_X_FORWARDED_HOST' that contains the original IP.

I've attached a patch that uses this address if it's available, else it does take the normal 'REMOTE_ADDR' key into account.

Shouldn't this be closed as duplicate?

wontfix is fine. I'd go so far as to say invalid because HTTP requests are not usable in the manner suggested by OP. You'd have a CVE slapped on WordPress trunk faster than you can finish beta testing.
