Statement: In order to exploit this flaw, an attacker would need to obtain a user's session cookie after the user has logged out but before the server-side credential cache expires. Typically, this will not be possible because browsers protect the cookie while it is valid a

CVE-2019-14826 ipa: Session not terminated after logout
A flaw was found in FreeIPA. Old session cookies can be reused after logout leading to session stealing.
