Summary

The `make_graphql_filter()` and `make_graphql_filter_sync()` filters of `juniper_warp` read the whole body of a POST request into memory before they parsed the body. The filters had no limit on the size of the body. A client could thus send a large body and exhaust the memory of the server. The request needs no authentication.

`juniper_warp` 0.9.1 reads at most 2 MiB of a request body by default. The filters respond with `413 Payload Too Large` to larger bodies. `make_graphql_filter_with_body_limit()` and `make_graphql_filter_sync_with_body_limit()` set another limit.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
