Security vulnerabilities

Drupal 7.26 and 6.30 were released in response to the discovery of security vulnerabilities. Details can be found in the official security advisory:

To fix the security problem, please upgrade to either Drupal 7.26 or Drupal 6.30.

Known issues

(Drupal 7 only) On sites with a very large number of unpublished nodes in the database, the Taxonomy module update function introduced in this release may take a very long time to run and consume an excessive amount of memory; see this issue. The solution is to upgrade directly to Drupal 7.28 instead.
