CVE-2023-22460
go-ipld-prime json codec may panic if asked to encode bytes
go-ipld-prime is an implementation of the InterPlanetary Linked Data (IPLD) spec interfaces, a batteries-included codec implementations of IPLD for CBOR and JSON, and tooling for basic operations on IPLD objects. Encoding data which contains a Bytes kind Node will pass a Bytes token to the JSON encoder which will panic as it doesn't expect to receive Bytes tokens. Such an encode should be treated as an error, as plain JSON should not be able to encode Bytes. This only impacts uses of the json codec. dag-json is not impacted. Use of json as a decoder is not impacted. This issue is fixed in v0.19.0. As a workaround, one may prefer the dag-json codec, which has the ability to encode bytes.

go-ipld-prime/codec/json may panic if asked to encode bytes
go-ipld-prime is a series of Go interfaces for manipulating IPLD data and a Go module that contains the go-ipld-prime/codec/json codec.
Impact
Encoding data which contains a Bytes kind Node will pass a Bytes token to the JSON encoder which will panic as it doesn't expect to receive Bytes tokens. Such an encoding should be treated as an error, as plain JSON should not be able to encode Bytes.
This only impacts uses of the "json" codec, "dag-json" is not impacted. Use of "json" as a decoder is not impacted.
Patches
Fixed in v0.19.0.
Workarounds
Prefer the "dag-json" codec which has the ability to encode bytes.

Panic in encoding in github.com/ipld/go-ipld-prime
Encoding data using the 'json' codec which contains a 'Bytes' type Node will cause the encoder to panic. The decoder is not impacted. If the codec is used to encode user supplied data, this may be used as a vector for a denial of service attack.
