Several vulnerabilities were discovered in smarty3, a template engine for PHP.

  • CVE-2018-13982

    path traversal vulnerability due to insufficient sanitization of code in Smarty templates. This allows attackers controlling the Smarty template to bypass the trusted directory security restriction and read arbitrary files.

  • CVE-2021-26119

    allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox mode.

  • CVE-2021-26120

For Debian 9 stretch, these problems have been fixed in version 3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u2.
