An issue was discovered in Enalean Tuleap 9.6 and prior versions. The vulnerability exists because the User::getRecentElements() method is using the unserialize() function with a preference value that can be arbitrarily manipulated by malicious users through the REST API interface, and this can be exploited to inject arbitrary PHP objects into the application scope, allowing an attacker to perform a variety of attacks (including but not limited to Remote Code Execution).
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
