[email protected] reports:
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.
