Last modified
CVE-2015-6831 is a high-severity vulnerability rated 7.3/10 on the CVSS scale. Multiple use-after-free vulnerabilities in SPL in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allow remote attackers to execute arbitrary code via vectors involving (1) ArrayObject, (2) SplObjectStorage, and (3) SplDoublyLinkedList, which are mishandled during unserialization.. EPSS estimates a 7.06% chance of exploitation in the next 30 days.
