Now, path resolution operates on a byte buffer using index-based backtracking for '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations.","state":0,"publishedAt":"2026-08-13T22:17:22.44+00:00","modifiedAt":"2026-09-03T16:37:52.17+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · 134c704f-9b21-4f2e-91b3-4a467353bcc0 · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://go.dev/cl/803681","https://go.dev/issue/80494","https://groups.google.com/g/golang-announce/c/94pEornpRlI","https://pkg.go.dev/vuln/GO-2026-6218"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-56860","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-407"],"productCriteria":[],"sourceDates":{"published":"2026-08-13T22:17:22.440","lastModified":"2026-09-03T16:37:52.170"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
