Summary

django-haystack versions from 3.0 before 3.4.0 are affected. The _to_python function in the Elasticsearch backend does not neutralize directives in code it evaluates, so the result_class argument of the more_like_this template tag can inject code (CWE-95). A remote attacker with high privileges can exploit this, and a public exploit is referenced.
