This release contains no other bug fixes or new features and is released for users who are unable to upgrade to ChiliProject 3.5.1. It is suitable for use on production websites running ChiliProject 2.x and we highly recommend that 2.x users download and install the security release as soon as possible. Users still running an old 1.x install are strongly encouraged to update to a more recent version as that branch is not supported any more and doesn’t receive updates.
2.8.1 contains 1 security fix for Rails. To quote the impact section from the announcement to the Rails security list:
Due to the way Active Record interprets parameters in combination with the way that JSON parameters are parsed, it is possible for an attacker to issue unexpected database queries with “IS NULL” or empty where clauses. This issue does *not* let an attacker insert arbitrary values into an SQL query, however they can cause the query to check for NULL or eliminate a WHERE clause when most users wouldn’t expect it.
All users running an affected release should either upgrade or use one of the work arounds immediately. All users running an affected release should upgrade immediately. Please note, this vulnerability is a variant of CVE-2012-2660, and CVE-2012-2694. Even if you upgraded to address those issues, you must take action again.
