Short explanation

An improper session invalidation after authentication credential change vulnerability in ash_authentication allows an attacker holding a victim's session token to remain signed in after the victim resets or changes their password.

Show the technical text from the sources

Improper Session Invalidation after Authentication Credential Change vulnerability in team-alembic ash_authentication allows an attacker holding a victim's session token to stay signed in after the victim resets or changes their password. With apply_on_password_change? true, AshAuthentication.AddOn.LogOutEverywhere.Transformer adds OnPasswordChange to update actions as a global change guarded by where: changing(hashed_password). That condition is evaluated before the action's before_action hooks run, but AshAuthentication.Strategy.Password.HashPasswordChange sets the new hash in a before_action hook, so for every non-atomic password change the condition is false and the user's stored tokens are not revoked. The generated password reset action and the installer's change_password action are both non-atomic. This issue affects ash_authentication: from 4.5.0 before 4.15.1 and from 5.0.0-rc.0 before 5.0.0-rc.16.
