Admin Self-Approval via Weak Confirmation Token in Extension

Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: TYPO3

Description
The extension fails to require the dedicated admin confirmation token when processing an admin-approval request, so a regular user confirmation hash, obtainable by any visitor through the public resend-confirmation action, is sufficient to self-approve a pending account awaiting admin approval.

Executive Summary

This vulnerability allows a regular user to self-approve an account that is pending admin approval by using a confirmation hash obtained through a public action. The system fails to require a dedicated admin confirmation token, making the regular user confirmation hash sufficient for approval.

Detection Guidance

This vulnerability involves insufficient validation of admin confirmation tokens, allowing regular user hashes to approve pending accounts. Detection requires checking application logs for admin-approval requests using non-admin tokens and monitoring for unusual account approvals without proper admin confirmation.

Impact Analysis

An attacker could exploit this to gain unauthorized access to an account awaiting admin approval without needing admin privileges. This could lead to unauthorized actions, data breaches, or privilege escalation within the system.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. It undermines access control measures, potentially resulting in non-compliance with data protection regulations.

Mitigation Strategies

Immediately update the affected extension to the latest patched version. Review and restrict user permissions to prevent unauthorized account approvals. Monitor admin approval queues for suspicious activity.
