Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: latte/latte versions prior to 2.10.6

Description: The issue allows bypassing of allowFunctions restrictions, affecting the security of the application. When the template is set to allow or disallow certain functions, adding control characters (x00-x08) after the function bypasses these restrictions.

Recommendations: For versions prior to 2.10.6, update to version 2.10.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of functions that can be bypassed by control characters until a patch is applied. Avoid using control characters (x00-x08) after functions in templates to minimize the risk of exploitation.
