{"id":"CVE-2026-86590","details":"In Eclipse Che versions 7.79.0 through 7.121.0, the dashboard backend's POST /dashboard/api/data/resolver endpoint passes a caller-supplied URL directly to an outbound HTTP GET request with no host filtering. An authenticated user can exploit this server-side request forgery (SSRF) to read responses from internal network addresses, including the cloud instance metadata service (169.254.169.254), loopback interfaces, RFC-1918 private ranges, and in-cluster Kubernetes services. The operator-configured allowlist (spec.devEnvironments.allowedSources.urls) is not consulted. The vulnerability is fixed in version 7.122.0, which adds private-address blocking, IPv4-mapped IPv6 bypass prevention, operator allowlist enforcement, and disables HTTP redirects on the outbound request.","modified":"2026-09-10T03:48:30.153939855Z","published":"2026-09-08T09:15:25.594Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86590.json","cna_assigner":"eclipse","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/617"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86590.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86590"},{"type":"FIX","url":"https://github.com/eclipse-che/che-dashboard/pull/1655"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-che/che-dashboard","events":[{"introduced":"db0b0859b3481fb34e178f4d789a7f11b07f19b9"},{"fixed":"ab1beea71f8d1eb3b7b52b02d245624a2f53022b"}],"database_specific":{"extracted_events":[{"introduced":"7.79.0"},{"fixed":"7.122.0"},{"fixed":"7.121.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86590.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
