CVE-2019-8341

An issue was discovered in Jinja2 2.10. The from_string function is prone to Server Side Template Injection (SSTI) where it takes the "source" parameter as a template object, renders it, and then returns it. The attacker can exploit it with {{INJECTION COMMANDS}} in a URI. NOTE: The maintainer and multiple third parties believe that this vulnerability isn't valid because users shouldn't use untrusted templates without sandboxing

Red Hat Product Security does not believe this CVE assignment is valid. To the best of our knowledge, Jinja2 does not make any guarantees about being able to safely handle untrusted data by default without sandboxing modes enabled.
