First published: Thu Nov 23 2023(Updated: )
### Impact If successful login attempts are recorded, the raw tokens are stored in the log table. If a malicious person somehow views the data in the log table, he or she can obtain a raw token, which can then be used to send a request with that user's authority. When you (1) **use the following authentiactors**, - [AccessTokens](https://codeigniter4.github.io/shield/references/authentication/tokens/) (`tokens`) - [JWT](https://codeigniter4.github.io/shield/addons/jwt/) (`jwt`) - [HmacSha256](https://codeigniter4.github.io/shield/references/authentication/hmac/) (`hmac`) and you (2) **log successful login attempts**, the raw tokens are stored. ### Patches Upgrade to Shield v1.0.0-beta.8 or later. ### Workarounds Disable logging for successful login attempts by the configuration files. - AccessTokens or HmacSha256 - Set `Config\AuthToken::$recordLoginAttempt` to `Auth::RECORD_LOGIN_ATTEMPT_FAILURE` or `Auth::RECORD_LOGIN_ATTEMPT_NONE` - JWT - Set `Config\AuthJWT::$recordLoginAttempt` to `Auth::RECORD_LOGIN_ATTEMPT_FAILURE` or `Auth::RECORD_LOGIN_ATTEMPT_NONE` ### References - https://codeigniter4.github.io/shield/getting_started/authenticators/ ### For more information If you have any questions or comments about this advisory: * Open an issue or discussion in [codeigniter4/shield](https://github.com/codeigniter4/shield) * Email us at [security@codeigniter.com](mailto:security@codeigniter.com)
