Alpine: py3-jinja2: security update to 3.1.4-r0

medium Tenable Cloud Security Plugin ID 408411

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar
 to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template,
 potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject
 arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to
 XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.
 (CVE-2024-22195)

 - Jinja is an extensible templating engine. The `xmlattr` filter in affected versions of Jinja accepts keys
 containing non-attribute characters. XML/HTML attributes cannot contain spaces, `/`, `>`, or `=`, as each
 would then be interpreted as starting a separate attribute. If an application accepts keys (as opposed to
 only values) as user input, and renders these in pages that other users see as well, an attacker could use
 this to inject other attributes and perform XSS. The fix for CVE-2024-22195 only addressed spaces but not
 other characters. Accepting keys as user input is now explicitly considered an unintended use case of the
 `xmlattr` filter, and code that does so without otherwise validating the input should be flagged as
 insecure, regardless of Jinja version. Accepting _values_ as user input continues to be safe. This
 vulnerability is fixed in 3.1.4. (CVE-2024-34064)
