Summary
TYPO3-EXT-SA-2025-001: Account Takeover in extension "OpenID Connect Authentication" (oidc)
Details
Problem Description
A vulnerability in the account linking logic of the extension allows a pre-hijacking attack leading to Account Takeover. The attack can only be exploited if the following requirements are met:
- An attacker can anticipate the email address of the user.
- An attacker can register a public frontend user account using that email address before the user's first OIDC login.
- The IDP returns the field email containing the email address of the user
Solution
An updated versions 4.0.0 is available from the TYPO3 extension manager, packagist and at https://extensions.typo3.org/extension/download/oidc/4.0.0/zip
Users of the extension are advised to update the extension as soon as possible.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
