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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-674"],"references":["https://github.com/ipld/go-ipld-prime/security/advisories/GHSA-w239-58x2-q8p5"],"products":[],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-42328","score":0.0012,"percentile":0.01822,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w239-58x2-q8p5","url":"https://osv.dev/vulnerability/GHSA-w239-58x2-q8p5","summary":"go-ipld-prime's DAG-CBOR and DAG-JSON decoders have unbounded recursion depth","modified":"2026-09-10T03:51:07.104837244Z","packages":[{"ecosystem":"Go","name":"github.com/ipld/go-ipld-prime","purl":"pkg:golang/github.com/ipld/go-ipld-prime","ranges":["<0.23.0"],"fixed":["0.23.0"]}]},{"id":"GO-2026-5684","url":"https://osv.dev/vulnerability/GO-2026-5684","summary":"Go-ipld-prime's DAG-CBOR and DAG-JSON decoders have unbounded recursion depth in github.com/ipld/go-ipld-prime","modified":"2026-07-24T19:00:25.418126532Z","packages":[{"ecosystem":"Go","name":"github.com/ipld/go-ipld-prime","purl":"pkg:golang/github.com/ipld/go-ipld-prime","ranges":["<0.23.0"],"fixed":["0.23.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
