A flaw was reported [1] in FreeIPA 4.0/4.1 where users could log in using only the OTP value. This arose because ipapwdauthentication() successfully determined that an empty password was invalid, but 389 itself would see this as an anonymous bind.
This will be fixed in the next release [2]. As support for OTP is not available in earlier versions, only FreeIPA >= 4.0 is affected.

Acknowledgements:
Red Hat would like to thank FreeIPA upstream for reporting this issue.
Statement:
This issue did not affect the versions of IPA as shipped with Red Hat Enterprise Linux 5, 6, or 7 as they did not include support for OTP.
An XSS flaw was reported in FreeIPA 4.x that could allow an administrator with lower privileges (such as sudo rights) to escalate their privileges to full administrator.
Earlier versions of FreeIPA/IPA do not suffer from this flaw.
Statement:
This issue did not affect the versions of IPA as shipped with Red Hat Enterprise Linux 6 or 7 as they do not include the vulerable Web UI code.
DISPUTED FreeIPA 4.x with API version 2.213 allows a remote authenticated users to bypass intended account-locking restrictions via an unlock action with an old session ID (for the same user account) that had been created for an earlier session. NOTE: Vendor states that issue does not exist in product and does not recognize this report as a valid security concern.
A flaw was found in all ipa versions 4.x.x through 4.8.0. When sending a very long password (>= 1,000,000 characters) to the server, the password hashing process could exhaust memory and CPU leading to a denial of service and the website becoming unresponsive. The highest threat from this vulnerability is to system availability.
