CVE-2026-44307: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in sqlalchemy mako
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.
