Multiple cross-site scripting (XSS) vulnerabilities in the MailChimp module 7.x-2.x before 7.x-2.7 for Drupal allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) a predictable "webhook URL key" and (2) improper sanitization of "Webhook variables from POST requests."

Security readout for executives and security teams

This flaw affected the Drupal MailChimp module, allowing attackers to inject script or HTML through MailChimp webhook handling. If a vulnerable site processed attacker-controlled webhook data, users or administrators could see malicious content in the site context. Exposure is limited to Drupal sites running the MailChimp contributed module 7.x-2.x before 7.x-2.7, particularly where webhook endpoints were configured and reachable. Treat as a focused remediation item for legacy Drupal estates. Prioritize internet-facing Drupal 7 sites using MailChimp webhooks, but do not escalate as actively exploited based on the provided evidence. Mitigation focus: Upgrade the Drupal MailChimp module to 7.x-2.7 or later.; Check Drupal project advisories for any additional module-specific guidance.; Restrict or disable unused MailChimp webhook endpoints where operationally possible..
