GHSA-33hq-fvwr-56pm

Under certain circumstances, serializing sparse arrays using uneval or stringify could cause CPU and/or memory exhaustion. When this occurs on the server, it results in a DoS. This is extremely difficult to take advantage of in practice, as an attacker would have to manage to create a sparse array on the server — which is impossible in every mainstream wire format — and then that sparse array would have to be run through uneval or stringify.

GHSA-8qm3-746x-r74r

Under certain circumstances, unevaling untrusted data can produce output code that will create objects with polluted prototypes when later evaled, meaning the output data can be a different shape from the input data.
