CVE-2021-26296

Severity CVSS v4.0:
Pending analysis
Type:
CWE-352 Cross-Site Request Forgery (CSRF)
Publication date:
19/02/2021
Last modified:
02/06/2021

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.
