CVE-2014-8684 is a vulnerability of currently unknown severity. CodeIgniter before 3.0 and Kohana 3.2.3 and earlier and 3.3.x through 3.3.2 make it easier for remote attackers to spoof session cookies and consequently conduct PHP object injection attacks by leveraging use of standard string comparison operators to compare cryptographic hashes.. EPSS estimates a 71.52% chance of exploitation in the next 30 days.
