{"cve":"CVE-2026-101048","nvd":{"published":"2026-09-27T18:16:31.313","modified":"2026-10-08T16:17:00.940","status":"Deferred","description":"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.","cvss_v4":{"vector":"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","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","score":5.4},"cwes":["CWE-863"],"references":["https://github.com/cloudreve/cloudreve/security/advisories/GHSA-v6w6-358x-2433","https://www.vulncheck.com/advisories/cloudreve-before-4.17.0-ssrf-via-admin-read-oauth-scope","https://github.com/cloudreve/cloudreve/security/advisories/GHSA-v6w6-358x-2433"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-101048","score":0.00235,"percentile":0.14293,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v6w6-358x-2433","url":"https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","summary":"Cloudreve Admin.Read OAuth tokens can trigger server-side node test requests","modified":"2026-09-28T03:55:28.333068843Z","packages":[{"ecosystem":"Go","name":"github.com/cloudreve/Cloudreve/v4","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v4","ranges":["<4.0.0-20260626022735-332a9d800205"],"fixed":["4.0.0-20260626022735-332a9d800205"]},{"ecosystem":"Go","name":"github.com/cloudreve/Cloudreve/v3","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v3","ranges":["<=3.0.0-20250225100611-da4e44b77af4"],"fixed":[]}]},{"id":"GO-2026-6106","url":"https://osv.dev/vulnerability/GO-2026-6106","summary":"Cloudreve Admin.Read OAuth tokens can trigger server-side node test requests in github.com/cloudreve/Cloudreve","modified":"2026-09-28T03:55:28.333068843Z","packages":[{"ecosystem":"Go","name":"github.com/cloudreve/Cloudreve","purl":"pkg:golang/github.com/cloudreve/Cloudreve","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/cloudreve/Cloudreve/v3","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v3","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/cloudreve/Cloudreve/v4","purl":"pkg:golang/github.com/cloudreve/Cloudreve/v4","ranges":["<4.0.0-20260626022735-332a9d800205"],"fixed":["4.0.0-20260626022735-332a9d800205"]}]}],"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).
