{"cve":"CVE-2026-85732","nvd":{"published":"2026-09-16T17:18:16.000","modified":"2026-09-16T18:17:18.070","status":"Deferred","description":"oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, the parseLink function in registry/remote/utils.go accepts an absolute URL from a registry-controlled Link response header without validating its scheme, host, or port. Tags, Referrers, and Repositories pagination operations then issue a GET request to the attacker-selected URL from the victim's network, allowing blind server-side request forgery against internal services. The response body is not returned to the attacker, but timing and error differences can reveal service reachability, and credentials may be attached when the credential store has an entry for the target host. Exploitation requires a victim to perform a pagination-based listing operation against a malicious registry. The maintainer identifies this report as a duplicate of GHSA-3hr5-mjrr-hfjh and states that remediation is consolidated in that earlier advisory. The consolidated issue is fixed in version 2.6.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N","score":4.7},"cwes":["CWE-918"],"references":["https://github.com/oras-project/oras-go/commit/31da1963f8c327dd089cd29faeae95cf0fc50842","https://github.com/oras-project/oras-go/releases/tag/v2.6.2","https://github.com/oras-project/oras-go/security/advisories/GHSA-h7vf-4x9w-h99v","https://github.com/oras-project/oras-go/security/advisories/GHSA-h7vf-4x9w-h99v"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-85732","score":0.00384,"percentile":0.32498,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h7vf-4x9w-h99v","url":"https://osv.dev/vulnerability/GHSA-h7vf-4x9w-h99v","summary":"oras-go: Blind SSRF via unvalidated Link header URL in pagination allows internal network probing","modified":"2026-10-01T20:55:52.275640599Z","packages":[{"ecosystem":"Go","name":"oras.land/oras-go/v2","purl":"pkg:golang/oras.land/oras-go/v2","ranges":["<2.6.2"],"fixed":["2.6.2"]}]},{"id":"GO-2026-6497","url":"https://osv.dev/vulnerability/GO-2026-6497","summary":"Blind SSRF via unvalidated Link header URL in pagination allows internal network probing in oras.land/oras-go","modified":"2026-10-01T20:45:12.219872881Z","packages":[{"ecosystem":"Go","name":"oras.land/oras-go/v2","purl":"pkg:golang/oras.land/oras-go/v2","ranges":["<2.6.2"],"fixed":["2.6.2"]}]}],"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).
