CVE-2024-22195
The
xmlattrfilter in affected versions of Jinja accepts keys containing spaces. XML/HTML attributes cannot contain spaces, as each would then be interpreted as 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. Note that accepting keys as user input is not common or a particularly intended use case of thexmlattrfilter, and an application doing so should already be verifying what keys are provided regardless of this fix.CVE-2024-34064
The
xmlattrfilter 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 the previous GHSA-h5c8-rqwp-cp95 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
xmlattrfilter, 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.Release Notes
pallets/jinja (jinja2)
v3.1.4Compare Source
Released 2024-05-05
xmlattrfilter does not allow keys with/solidus,>greater-than sign, or
=equals sign, in addition to disallowing spaces.Regardless of any validation done by Jinja, user input should never be used
as keys to this filter, or must be separately validated first.
