CVE-2014-2983: Drupal 6.x before 6.31 and 7.x before 7.27 does not properly isolate the cached data of different anonymous...

Security readout for executives and security teams

Older Drupal 6 and 7 sites could leak sensitive information typed into forms by anonymous visitors because cached data was not properly separated between users. The source bundle says this could happen opportunistically, not predictably. It is mainly a confidentiality issue for public Drupal sites that collect sensitive form input. Exposure is likely limited to Drupal 6.x before 6.31 and Drupal 7.x before 7.27, especially public sites allowing anonymous users to submit forms containing sensitive data. Prioritize remediation for internet-facing Drupal sites that collect personal, credential, payment, or business-sensitive form data. Urgency is lower than a confirmed code-execution issue, but confidentiality exposure can still create regulatory and customer-impact risk. Mitigation focus: Upgrade Drupal 6 sites to 6.31 or later where still applicable.; Upgrade Drupal 7 sites to 7.27 or later where still applicable.; Apply relevant Debian security updates if Drupal is installed from Debian packages..
