Original source description

Impact

secretKey, an important key for HMAC SHA256 authentication, was stored in the database in raw form.

Patches

Upgrade to Shield v1.0.0-beta.8 or later.

After upgrading, all existing secret keys must be encrypted. See https://github.com/codeigniter4/shield/blob/develop/UPGRADING.md for details.
