Prior to 0.22.0, the DAG-CBOR decoder uses collection sizes declared in CBOR headers as Go preallocation hints for maps and lists. The decoder does not cap these size hints or account for their cost in its allocation budget, allowing small payloads to cause excessive memory allocation. This vulnerability is fixed in 0.22.0.","state":0,"publishedAt":"2026-04-07T15:17:45.117+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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-378j-3jfj-8r9f"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35480","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-770"],"productCriteria":["cpe:2.3:a:protocol:go-ipld-prime:*:*:*:*:*:go:*:*"],"sourceDates":{"published":"2026-04-07T15:17:45.117","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
