要点
- CVE-2023-22460 は github.com/ipld/go-ipld-prime, go-ipld-prime (protocol) に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：1.1%（全脆弱性の 66.2% より高い）。
- 対処：0.19.0 以降に更新してください。
概要
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.
References
See fix in #472
NVD の説明
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.
