Unauthenticated Club Record Modification in WordPress Plugin

Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: TYPO3

Description
The extension resolves the targeted club record from a user-supplied request argument in its frontend edit, update, and activate actions, but performs no ownership check in any of them. An unauthenticated visitor who knows the UID of a club record can send a direct request to the update or activate action and overwrite that record, or publish one still awaiting approval, without owning it.

Executive Summary

This vulnerability is a Broken Access Control issue in the TYPO3 extension 'Club Directory'. It allows an unauthenticated attacker to modify or publish club records by knowing their UID and sending direct requests to update or activate actions without performing ownership checks.

Detection Guidance

Check for unauthorized modifications to club records by monitoring update or activate actions in the Club Directory extension logs. Look for requests targeting known UID values without proper authentication.

Impact Analysis

An attacker could overwrite existing club records or publish unapproved clubs without authorization. This could lead to misinformation, unauthorized changes, or disruption of club directory functionality.

Compliance Impact

This vulnerability could lead to unauthorized data modifications, potentially violating integrity and access control requirements in GDPR and HIPAA. Unauthorized changes to records may result in non-compliance with data accuracy and protection standards.

Mitigation Strategies

Update the Club Directory extension to version 8.1.3 or later immediately via the TYPO3 extension manager, Packagist, or official repository to patch the broken access control flaw.
