Security readout for executives and security teams
CVE-2015-6660 affects Drupal 6 and 7 sites where Form API token validation could be bypassed for certain file-upload callbacks. An attacker could trick an authenticated user into causing file uploads under that user’s account. The source bundle does not provide CVSS, public exploit evidence, or KEV listing. Exposure is most likely on legacy Drupal 6 or Drupal 7 installations below 6.37 or 7.39, including distro-packaged Drupal noted by Debian and Fedora advisories. Sites without file upload features may have lower practical exposure, but the bundle does not define affected configurations beyond Drupal core versions. Treat as a legacy-platform hygiene issue with moderate urgency. Prioritize internet-facing Drupal 6 or 7 sites, especially those supporting user file uploads. There is no provided evidence of active exploitation, but unsupported or unpatched Drupal should already be on a remediation track. Mitigation focus: Upgrade Drupal 6 to 6.37 or later, if still maintained in your environment.; Upgrade Drupal 7 to 7.39 or later.; Apply relevant Debian or Fedora package updates where Drupal is OS-packaged..
