django CMS 2.1.4 security release issued

Aug. 24, 2011

This afternoon a possible security issue in our text plugin was brought to our attention. All django CMS versions are affected, and as a result we released version 2.1.4. Thanks go to Klaas van Schelven for reporting this issue.

The security issue fixed in this release allowed users with administrator accounts that have the right to edit pages to inject javascript into text plugins which could allow them to hijack user accounts with higher permission levels than themselves. As a result, no javascript is allowed in the text plugins anymore, and the 2.1.4 release contains a migration script to clean all existing plugins. The snippet plugin, which also has this flaw, continues to allow javascript and should therefore be used very cautiously.

Full list of changes in this release

  • No longer allow javascript in text plugins.
  • Clean all javascript from text plugins
  • Added html5lib as a dependency to do the javascript filtering.

Affected versions

  • all versions

Detailed upgrade instructions

Update your django CMS to 2.1.4 and run the south migration using the `migrate text` management command.
