The invites feature allows users to accept the invitation for an unlimited amount of time through the password reset functionality.
When using the password reset functionality, the devise_invitable gem always accepts the pending invitation if the user has been invited as shown in this piece of code within the devise_invitable gem:
https://github.com/scambra/devise_invitable/blob/41f58970ff76fb64382a9b9ea1bd530f7c3adab2/lib/devise_invitable/models.rb#L198
The only check done here is if the user has been invited but the code does not ensure that the pending invitation is still valid as defined by the invite_for expiry period as explained in the gem's documentation:
https://github.com/scambra/devise_invitable#model-configuration-
invite_for: The period the generated invitation token is valid. After this period, the invited resource won’t be able to accept the invitation. Wheninvite_foris0(the default), the invitation won’t expire.
Decidim sets this configuration to 2.weeks so this configuration should be respected:
https://github.com/decidim/decidim/blob/d2d390578050772d1bdb6d731395f1afc39dcbfc/decidim-core/config/initializers/devise.rb#L134
The bug is in the devise_invitable gem and should be fixed there and the dependency should be upgraded in Decidim once the fix becomes available.
Update devise_invitable to version 2.0.9 or above by running the following command:
$ bundle update devise_invitable
The invitations can be cancelled directly from the database by running the following command from the Rails console:
> Decidim::User.invitation_not_accepted.update_all(invitation_token: nil)
