Description Pedro Sampaio 2021-02-18 20:08:01 UTC 
In the default configuration, Apache MyFaces Core versions 2.2.0 to 2.2.13, 2.3.0 to 2.3.7, 2.3-next-M1 to 2.3-next-M4, and 3.0.0-RC1 use cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult)
for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application.

Statement:

Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of RHOSP 14 and is only receiving security fixes for Important and Critical flaws.
