{"id":"CVE-2026-101048","summary":"Cloudreve before 4.17.0 SSRF via Admin.Read OAuth scope","details":"Cloudreve before 4.17.0 registers the administrative node test endpoints (POST /api/v4/admin/node/test and POST /api/v4/admin/node/test/downloader) without requiring the Admin.Write OAuth scope, unlike the node create/update/delete routes. An OAuth client that has been authorized by an administrator with only the Admin.Read scope can therefore submit attacker-controlled node definitions and cause the Cloudreve server to issue outbound requests to arbitrary URLs, enabling blind server-side request forgery, internal service probing, and delivery of signed Cloudreve slave-style requests to attacker-chosen endpoints.","aliases":["GHSA-v6w6-358x-2433","GO-2026-6106"],"modified":"2026-09-29T03:45:41.509793881Z","published":"2026-09-27T17:02:36.546Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101048.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101048.json"},{"type":"ADVISORY","url":"https://github.com/cloudreve/cloudreve/security/advisories/GHSA-v6w6-358x-2433"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-101048"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cloudreve-before-4.17.0-ssrf-via-admin-read-oauth-scope"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cloudreve/cloudreve","events":[{"introduced":"0"},{"fixed":"d4a145c3ac68f08b9071dec0f2ac025c6dc7362d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.17.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["4.16.1","4.16.0","4.15.0","4.14.1","4.14.0","4.13.0","4.12.1","4.12.0","4.11.1","4.11.0","4.10.1","4.10.0","4.9.2","4.9.1","4.9.0","4.8.0","4.7.0","4.6.0","4.5.1","4.5.0","4.4.1","4.4.0","4.3.0","4.2.0","4.1.3","4.1.2","4.1.1","4.1.0","4.0.0","4.0.0-beta.14","4.0.0-beta.13","4.0.0-beta.12","4.0.0-beta.11","4.0.0-beta.10","4.0.0-beta.9","4.0.0-beta.8","4.0.0-beta.7","4.0.0-beta.6","3.8.3","3.8.2","3.8.1","3.8.0","3.8.0-beta1","3.7.1","3.7.0","3.6.2","3.6.1","3.6.0","3.6.0-beta1","3.5.3","3.5.2","3.5.1","3.5.0","3.5.0-beta.3","3.5.0-beta2","3.5.0-beta1","3.4.2","3.4.1","3.4.0","3.4.0-beta1","3.3.2","3.3.1","3.3.0","3.2.1","3.2.0","3.1.1","3.1.0","3.0.0","3.0.0-rc1","3.0.0-beta3","3.0.0-beta2","3.0.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-101048.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:L/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
