AI-suggested
Upgrade Mako to version 1.3.12 or later, where this path traversal vulnerability is fixed. Since the vendor advisory states the issue is resolved in 1.3.12, applying this official fix fully mitigates the vulnerability. No additional mitigations are specified or required.
Description
Mako is a template library written in Python. Prior to 1.3.12, on Windows, a URI using backslash traversal (e.g. \..\..\ secret.txt) bypasses the directory traversal check in Template.__init__ and the posixpath-based normalization in TemplateLookup.get_template(), allowing reads of files outside the configured template directory. This vulnerability is fixed in 1.3.12.
