Summary

Improper Restriction of Security Token Assignment vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. Previously issued administrative tokens were not invalidated after an administrator account was suspended, deleted, or deactivated, allowing continued access to administrative APIs until the token expired.
