It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-645 advisory.

    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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
