[dependabot]

Bumps mako from 1.4.1 to 1.4.2.

Release notes

Sourced from mako's releases.

1.4.2

Released: Tue Sep 22 2026

bug

• [bug] [tests] Adjusted the test suite to accommodate for a change in Pygments 2.21.0 where the HtmlFormatter now renders " and ' characters literally rather than as HTML entities, which caused failures in tests that assert against the rendered output of html_error_template().

  References: #440

• [bug] [template] Fixed issue in TemplateLookup where a URI beginning with a drive designator (e.g. C:/../../secret.txt) could bypass the directory traversal check on Windows, allowing reads of arbitrary files outside of the template directory. The check in Template normalized the URI using os.path, which on Windows is ntpath; as ntpath splits the drive designator off and treats the remainder as rooted, the .. segments were absorbed before the check could inspect them. Normalization is now performed with posixpath, which is the same module used by TemplateLookup.get_template() to resolve the URI to a file.
