The CVE-2018-1000533 vulnerability was detected in GitList version <= 0.6, where an incorrectly sanitized system function rendered the software open to remote code execution. This vulnerability was caused by the inappropriate input sanitization in the "searchTree" function, which when prompted with malious code can execute any code as the PHP user. This vulnerability was first identified by a security expert, Mathias Karlsson, in May 2018, after which the GitList community released a security update to fix the issue.
