The root cause of this is vulnerable implementation of OP side.

So something should be done in OP side eventually.

But in the mean while, there could be some workaround which RP itself can do.

One is stop using private associations and using only shared associations in RP side.
I guess you can do this with zimbraOpenidConsumerStatelessModeEnabled attribute in ZimbraLDAP if you use OpenID Consumer server extension in Zimbra NE package.
(I can only "guess" that because i can not find source code of OpenID Consumer server extension in Zimbra.:p)
