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.","state":0,"publishedAt":"2026-05-27T16:31:38.09+00:00","modifiedAt":"2026-05-28T14:14:09.825+00:00","affected":[{"ecosystem":"Vendor product","name":"go-ipld-prime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ipld\",\n                    \"product\": \"go-ipld-prime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.23.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/ipld/go-ipld-prime/security/advisories/GHSA-w239-58x2-q8p5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-42328","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-42328","identifiers":["CVE-2026-42328"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
