Forum OpenACS Development: Re: XSS vulnerability in XoWiki and a lot of other OpenACS pages
This patch should work for you (i could not test it here). However, in general i would certainly recommend to upgrade; check, if you got an error during running the upgrade scripts (for every upgrade, you see a message "-- upgrading to" in the error log). Check, if upgrade worked correctly. I might be able to connect to the internet later this day.
