Description
Security researcher Ali Razzaq has discovered that confirming an opt-in token does not invalidate previous opt-in tokens in Contao 4.7.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|

4.7.3 |
| contao/core-bundle | >= 4.7.0, < 4.7.3 |
4.7.3 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-287: Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
How to prevent it
- Architecture and Design: Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CWE-324: Use of a Key Past its Expiration Date
The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key.
How to prevent it
- Architecture and Design: Adequate consideration should be put in to the user interface in order to notify users previous to the key's expiration, to explain the importance of new key generation and to walk users through the process as painlessly as possible.
