A user disabled on a wiki using email verification for registration can re-activate himself by using the activation link provided for his registration.
The problem has been patched in the following versions of XWiki: 11.10.13, 12.6.7, 12.10.2, 13.0.
It’s possible to workaround the issue by resetting the
validkey property of the disabled XWiki users. This can be done by editing the user profile with object editor.
