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.","categories":["Libraries & packages"],"product":"cloudreve","vendor":"cloudreve","ecosystem":"Go","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101048","source_modified_at":"2026-10-08T15:22:07.489Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"cloudreve","vendor":"cloudreve","versions":[{"lessThan":"4.17.0","status":"affected","version":"0","versionType":"semver"},{"status":"unaffected","version":"4.17.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","source_modified_at":"2026-09-28T03:55:28.333068843Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"github.com/cloudreve/Cloudreve/v4","ecosystem":"Go","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v4"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.0.0-20260626022735-332a9d800205"}]}],"versions":[]},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","source_modified_at":"2026-09-28T03:55:28.333068843Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"github.com/cloudreve/Cloudreve/v3","ecosystem":"Go","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"3.0.0-20250225100611-da4e44b77af4"}]}],"versions":[]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101048","source_modified_at":"2026-10-08T15:22:07.489Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"cloudreve","ecosystem":null},"version":"4.17.0","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","source_modified_at":"2026-09-28T03:55:28.333068843Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"github.com/cloudreve/Cloudreve/v4","ecosystem":"Go","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v4"},"version":"4.0.0-20260626022735-332a9d800205"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00188,"percentile":0.07943,"score_date":"2026-10-23"},"published_at":"2026-09-27T17:02:36.546Z","modified_at":"2026-10-08T15:22:07.489Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101048","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T15:22:07.489Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T03:55:28.333068843Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101048","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/cloudreve/cloudreve/security/advisories/GHSA-v6w6-358x-2433","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/cloudreve-before-4.17.0-ssrf-via-admin-read-oauth-scope","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T15:30:07.809939Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-08T15:22:07.489Z","content_hash":"be410c62c992279850411569c98ed5aef428f4ca5c9ecdb3d74021a461ae65b4"}}
