SA-CONTRIB-2012-173 - Nodewords: Information disclosure

This module enables you to assign meta tags on Drupal 6 sites to aid with 3rd party search indexing and sharing on social networks.

The module doesn’t correctly filter node content when configured to automatically generate descriptions meta tags from the node text. This lack of filtering could allow some code, e.g. BBCode, to pass through unprocessed and potentially display private or otherwise secret information, links, file paths or other potentially sensitive details. The problem affects the normal ‘description’ meta tag along with the ‘dc.description’ and ‘og:description’ meta tags, all of which used the same logic.

This vulnerability is mitigated by the fact that it is unlikely that sensitive content would be within the extracted portion.
