Details
A vulnerability has been found in ipld go--prime up to 0.22.x and classified as problematic. This vulnerability affects some unknown functionality of the component DAG-JSON Decoder. The manipulation with an unknown input leads to a recursion vulnerability. The CWE definition for the vulnerability is CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. As an impact it is known to affect availability. CVE summarizes:
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.
The advisory is available at github.com. This vulnerability was named CVE-2026-42328 since 04/26/2026. The exploitation appears to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available.
Upgrading to version 0.23.0 eliminates this vulnerability.
