CVE-2026-47228 Admidio CVE debrief

Who should care

Defenders responsible for Admidio user management solution deployments should assess exposure and apply the patch to prevent potential password reset attacks. They should review user management configurations, ensure secure password reset processes, and monitor for potential exploitation attempts. Security teams and vulnerability management teams should prioritize verifying exposure and applying the patch.

Why it matters

CVE-2026-47228 allows an attacker to reset a user's password without validation, impacting Admidio user management solution deployments. Defenders should verify exposure and apply the patch.

• Password reset without interaction
• Potential unauthorized access to user accounts
• Need to verify exposure and apply patch

Technical summary

The `modules/registration.php` file in Admidio has a mode `send_login` that regenerates a random password for a user and emails it in cleartext without validating a CSRF token. This allows an attacker to reset a user's password if the request is issued as a top-level navigation by a registration-administrator. The issue arises from the lack of CSRF token validation in the `send_login` branch, unlike other state-changing modes in the same file. The vulnerability impacts Admidio user management solution deployments, allowing potential unauthorized access to user accounts.

Defensive priority

Defenders should prioritize verifying exposure and applying the patch, as the vulnerability allows password reset without interaction.

Recommended defensive actions

• Verify if Admidio version is prior to 5.0.10 and apply the patch if necessary
• Review user management configurations and ensure secure password reset processes
• Monitor for potential exploitation attempts
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, its impact, and the fix in version 5.0.10.
