Apache: >> Couchdb >> 3.3.0 Security Vulnerabilities
Design document functions which receive a user http request object may expose authorization or session cookie headers of the user who accesses the document.
These design document functions are:
* list
* show
* rewrite
* update
An attacker can leak the session component using an HTML-like output, insert the session as an external resource (such as an image), or store the credential in a _local document with an "update" function.
For the attack to succeed the attacker has to be able to insert the design documents into the database, then manipulate a user to access a function from that design document.
Workaround: Avoid using design documents from untrusted sources which may attempt to access or manipulate request object's headers

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.
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.
