Smarty_Security::isTrustedResourceDir() in Smarty before 3.1.33 is prone to a path traversal vulnerability due to insufficient template code sanitization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
