[dependabot]

Bumps mako from 1.3.10 to 1.3.12.

Release notes

Sourced from mako's releases.

1.3.12

Released: Tue Apr 28 2026

bug

• [bug] [template] Fixed issue in TemplateLookup where a URI with backslash path separators (e.g. \..\secret.txt) could bypass the directory traversal check on Windows, allowing reads of arbitrary files outside of the template directory. Backslash characters in URIs are now normalized to forward slashes before path resolution.

  References: #435

1.3.11

Released: Tue Apr 14 2026

bug

• [bug] [template] Fixed issue in TemplateLookup where a URI with a double-slash prefix (e.g. //../../) could bypass the directory traversal check in Template, allowing reads of arbitrary files outside of the template directory. The issue was caused by an inconsistency in how leading slashes were stripped between TemplateLookup.get_template() and Template initialization.
