Echo: mako: security update to 1.3.10+echo.1

high Tenable Cloud Security Plugin ID 457906

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Mako is a template library written in Python. Prior to 1.3.11, TemplateLookup.get_template() is vulnerable
 to path traversal when a URI starts with // (e.g., //../../../secret.txt). The root cause is an
 inconsistency between two slash-stripping implementations. Any file readable by the process can be
 returned as rendered template content when an application passes untrusted input directly to
 TemplateLookup.get_template(). This vulnerability is fixed in 1.3.11. (CVE-2026-41205)

Solution

Update the mako library and its related packages to version 1.3.10+echo.1 or later.
