CVE-2013-4228: The OG access fields (visibility fields) implementation in Organic Groups (OG) module 7.x-2.x before 7.x-2....

Security readout for executives and security teams

CVE-2013-4228 is an access-control flaw in the Drupal Organic Groups module. On affected sites, logged-in users could reach private group content by guessing node IDs and subscribing to private groups. The main business risk is unintended disclosure of restricted community, customer, or internal content. Exposure is limited to Drupal sites using Organic Groups 7.x-2.x before 7.x-2.3, especially sites relying on private groups for confidentiality. The source bundle does not identify affected core Drupal versions or other products. Prioritize remediation for Drupal sites that use private groups to protect sensitive or customer-facing content. Lower urgency applies where Organic Groups is absent, groups are public, or affected versions are not deployed. Mitigation focus: Upgrade Organic Groups to 7.x-2.3 or later where applicable.; Review Drupal and Organic Groups vendor guidance for supported remediation.; Audit private group membership and content visibility settings..
