CVE-2021-26296

7.5 highEPSS 2.9%

High (7.5). EPSS 2.9% chance of exploitation in the next 30 days. Fixed in org.apache.myfaces.core:myfaces-core-module 2.0.25, 2.1.19, 2.2.14.

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.
