Security readout for executives and security teams
Plain-English summary
This issue affects Drupal sites using the Mass Contact module. A user who already has the "administer mass contact" permission could place script or HTML in a category label, creating cross-site scripting risk for people viewing that content.
Executive priority
Treat as a targeted cleanup item for legacy Drupal environments. Prioritize if the module is installed and administration permissions are broadly assigned; otherwise handle through normal vulnerability maintenance.
Technical view
CVE-2015-6807 is an authenticated stored XSS in Drupal Mass Contact module 6.x-1.x before 6.x-1.6 and 7.x-1.x before 7.x-1.1. The vulnerable input is the category label. The source bundle does not provide CVSS, CWE, exploit details, or broader product impact.
Likely exposure
Exposure is limited to Drupal installations running the Mass Contact module on the vulnerable 6.x-1.x or 7.x-1.x branches. Practical risk depends on whether untrusted or many users hold the "administer mass contact" permission.
Exploitation context
The bundle does not show KEV listing or active exploitation evidence. Exploitation requires an authenticated remote user with the specific Mass Contact administration permission and access to modify a category label.
Researcher notes
The available evidence identifies the vulnerable parameter and fixed version thresholds but lacks CVSS, CWE, exploit maturity, and detailed advisory text in the bundle. Avoid assuming unauthenticated exposure or active exploitation.
Mitigation direction
- Upgrade Mass Contact to 6.x-1.6 or 7.x-1.1 as applicable.
- Restrict "administer mass contact" to trusted administrators only.
- Review Drupal advisory guidance before production changes.
- Inspect existing category labels for unexpected HTML or script content.
Validation and detection
- Inventory Drupal sites for Mass Contact module installations.
- Confirm installed versions are not below the fixed releases.
- Review roles assigned "administer mass contact" permission.
- Audit Mass Contact category labels and recent privileged changes.
