CVSS v3.1

Official Description

CodeIgniter Shield is an authentication and authorization provider for CodeIgniter 4. In affected versions successful login attempts are recorded with the raw tokens stored in the log table. If a malicious person somehow views the data in the log table they can obtain a raw token which can then be used to send a request with that user's authority. This issue has been addressed in version 1.0.0-beta.8. Users are advised to upgrade. Users unable to upgrade should disable logging for successful login attempts by the configuration files.
