Vulnerability Name:

CVE-2018-13982 (CCN-149954)

Assigned:2018-09-17
Published:2018-09-17
Updated:2021-11-02
Summary:Smarty_Security::isTrustedResourceDir() in Smarty before 3.1.33 is prone to a path traversal vulnerability due to insufficient template code sanitization. This allows attackers controlling the executed template code to bypass the trusted directory security restriction and read arbitrary files.
