GHSA-MVV5-7C62-32XW
Vulnerability from github – Published: 2026-08-24 15:31 – Updated: 2026-08-24 15:31RansomLook contains insufficient resource validation in the analysis PDF generation functionality. Analysis documents are converted from Markdown to HTML and passed to WeasyPrint for PDF rendering. Prior to the fix, WeasyPrint used its default URL fetcher, allowing resource references contained in an analysis to be resolved without restrictions.
An authenticated attacker able to create or modify an analysis could embed crafted resource references using schemes such as file:// or http://. When the analysis was subsequently rendered as PDF, WeasyPrint would process these references with the privileges and network access of the RansomLook server.
A malicious file:// reference could cause the renderer to access arbitrary files readable by the RansomLook process, potentially exposing sensitive configuration, credentials, or other local data through rendered resources. Network URLs could cause the server to initiate requests to localhost, internal network services, or external systems, resulting in server-side request forgery (SSRF) and potentially bypassing network-level access restrictions.
The patch introduces a dedicated WeasyPrint URL fetcher that permits only data: resources, the RansomLook report logo, and files contained within the analysis asset directory. Network resources and filesystem paths outside these explicitly permitted locations are rejected.

Vulnerability from github – Published: 2026-04-15 19:43 – Updated: 2026-05-14 20:39Summary
NocoBase's workflow HTTP request plugin and custom request action plugin make server-side HTTP requests to user-provided URLs without any SSRF protection. An authenticated user can access internal network services, cloud metadata endpoints, and localhost.
Vulnerable Code
1. Workflow HTTP Request Plugin
packages/plugins/@nocobase/plugin-workflow-request/src/server/RequestInstruction.ts lines 117-128:
return axios.request({
url: trim(url), // User-controlled, no validation
method,
headers,
params,
timeout,
...(method.toLowerCase() !== 'get' && data != null
? { data: transformer ? await transformer(data) : data }
: {}),
});
The url at line 98 comes directly from user workflow configuration with only whitespace trimming.
2. Custom Request Action Plugin
packages/plugins/@nocobase/plugin-action-custom-request/src/server/actions/send.ts lines 172-198:
const axiosRequestConfig = {
baseURL: ctx.origin,
...options,
url: getParsedValue(url, variables), // User-controlled via template
headers: { ... },
params: getParsedValue(arrayToObject(params), variables),
data: getParsedValue(toJSON(data), variables),
};
const res = await axios(axiosRequestConfig); // No IP validation
Missing Protections
- No
request-filtering-agentor SSRF library (confirmed via grep across entire codebase) - No private IP range filtering
- No cloud metadata endpoint blocking
- No URL scheme validation
- No DNS rebinding protection
Attack Scenario
- Authenticated user creates a workflow with HTTP Request node
- Sets URL to
http://169.254.169.254/latest/meta-data/iam/security-credentials/ - Triggers the workflow
- Server fetches AWS metadata and returns IAM credentials in workflow execution logs
Alternatively via Custom Request action:
1. Create custom request with URL http://127.0.0.1:5432 or http://10.0.0.1:8080/admin
2. Execute the action
3. Server makes request to internal service
Impact
- Cloud metadata theft: AWS/GCP/Azure credentials via metadata endpoints
- Internal network access: Scan and interact with services on private IP ranges
- Database access: Connect to localhost databases (PostgreSQL, Redis, etc.)
- Authentication required: Yes (authenticated user), but any workspace member can create workflows

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
