ChiliProject 2.9.0 has just been released. This release is a security release to fix a severe security issue of Rails (CVE-2013-0333) which allows attackers to inject and execute arbitrary code on the server hosting ChiliProject. This bug was fixed in Rails 2.3.16, which is included in this release of ChiliProject.
This release contains no other bug fixes or new features and is released for users who are unable to upgrade to ChiliProject 3.6.0. 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 immediately.
2.9.0 contains 1 security fix for Rails. To quote the impact section from the announcement to the Rails security list:
The JSON Parsing code in Rails 2.3 and 3.0 support multiple parsing backends. One of the backends involves transforming the JSON into YAML, and passing that through the YAML parser. Using a specially crafted payload attackers can trick the backend into decoding a subset of YAML.
All users running an affected application should upgrade or use the workaround immediately.
