- validate_doc_update
- list
- filter
- filter views (using view functions as filters)
- rewrite
- update
This doesn't affect map/reduce or search (Dreyfus) index functions.
Users are recommended to upgrade to a version that is no longer affected by this issue (Apache CouchDB 3.3.2 or 3.2.3).
Workaround: Avoid using design documents from untrusted sources which may attempt to cache or store data in the Javascript environment.
