CVE-2021-26296

HIGH 7.5EPSS 3.03%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
