go-ipld-prime/codec/json may panic if asked to encode bytes

CVE-2023-22460 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

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.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
