-Details will be published on 2023-05-02
+Description
+===========
+
+Design documents with matching document IDs, from databases on the same
+cluster, may share a mutable Javascript environment when using these design
+document functions:
+
+  * 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.
+
+Mitigation
+==========
+
+CouchDB :ref:`3.3.2 <release/3.3.2>` and :ref:`3.2.3 <release/3.2.3>` and
+onwards matches Javascript execution processes by database names in addition to
+design document IDs when processing the affected design document functions.
+
+Workarounds
+===========
+
+Avoid using design documents from untrusted sources which may attempt to cache
+or store data in the Javascript environment.
