En resumen
- CVE-2023-22460 es una vulnerabilidad ALTO (CVSS 7.5) que afecta a github.com/ipld/go-ipld-prime, go-ipld-prime (protocol).
- Probabilidad de explotación en los próximos 30 días (EPSS): 1.1%, mayor que el 66.2% de las vulnerabilidades.
- Solución: actualizar a 0.19.0 o posterior.
Description
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 description
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.
