Description Vasyl Kaigorodov 2015-03-31 16:49:14 UTC
Zend\Validator\Csrf, starting in the Zend Framework 2.3 series, was not correctly identifying null or mal-formatted token identifiers, leading to false positive validations, and thus potentially allowing for Cross-Site Request Forgery vectors.

A patch was written that correctly identifies invalid token identifiers, ensuring that they invalidate the provided value.
It was discovered that the vulnerability was introduced specifically in the 2.3 series, and thus no patch was necessary against the 2.2 series.
