Vulnerability in github.com/ipld/go-ipld-prime (CVE-2026-42328)
Summary
Vulnerability in github.com/ipld/go-ipld-prime (CVE-2026-42328). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 0.23.0 or later.
Original description
The description as published by the source.
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. Prior to 0.23.0, the DAG-CBOR and DAG-JSON decoders recurse on each nested map or list without a depth limit. A payload containing deeply nested collections causes the decoder to recurse once per level, growing the goroutine stack until the Go runtime terminates the process with a fatal stack overflow (distinct from a recoverable panic). This vulnerability is fixed in 0.23.0.
