Vulnerability from github – Published: 2025-02-14 15:26 – Updated: 2025-02-14 22:18Description
Label Studio's S3 storage integration feature contains a Server-Side Request Forgery (SSRF) vulnerability in its endpoint configuration. When creating an S3 storage connection, the application allows users to specify a custom S3 endpoint URL via the s3_endpoint parameter. This endpoint URL is passed directly to the boto3 AWS SDK without proper validation or restrictions on the protocol or destination.
The vulnerability allows an attacker to make the application send HTTP requests to arbitrary internal services by specifying them as the S3 endpoint. When the storage sync operation is triggered, the application attempts to make S3 API calls to the specified endpoint, effectively making HTTP requests to the target service and returning the response in error messages.
This SSRF vulnerability enables attackers to bypass network segmentation and access internal services that should not be accessible from the external network. The vulnerability is particularly severe because error messages from failed requests contain the full response body, allowing data exfiltration from internal services.
Steps to reproduce
-
Create an account in Label Studio
-
Create a new project with basic configuration
-
Create an S3 storage connection with the following configuration:
json { "project": 1, "title": "Test Storage", "bucket": "<filename>", "s3_endpoint": "http://internal-web", "use_blob_urls": true, "aws_access_key_id": "test", "aws_secret_access_key": "test" } - Trigger a storage sync operation by sending a POST request to
/api/storages/s3/[storage_id]/sync
The application will attempt to connect to the specified endpoint URL as if it were an S3 service. When the request fails due to invalid S3 API responses, the error message will contain the raw response from the internal service, allowing access to internal resources.
Mitigations
- Implement strict validation of S3 endpoint URLs to allow only valid S3service endpoints
- Add an allowlist of endpoint domains and protocols
- Sanitize error messages to prevent leakage of sensitive information from failed requests
- Consider implementing network-level controls to restrict outbound connections from the application server
Impact
This vulnerability has high severity as it allows authenticated users to make requests to arbitrary internal services from the application server, potentially exposing sensitive internal resources and bypassing network segmentation. The inclusion of response data in error messages makes this particularly effective for data exfiltration.

Vulnerability from github – Published: 2025-09-29 21:30 – Updated: 2025-10-09 18:30Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (VA/SaaS deployments) contain a protection mechanism failure vulnerability within the file_get_contents() function. When an administrator configures a printer’s hostname (or similar callback field), the value is passed unchecked to PHP’s file_get_contents()/cURL functions, which follow redirects and impose no allow‑list, scheme, or IP‑range restrictions. An admin‑level attacker can therefore point the hostname to a malicious web server that issues a 301 redirect to internal endpoints such as the AWS EC2 metadata service. The server follows the redirect, retrieves the metadata, and returns or stores the credentials, enabling the attacker to steal cloud IAM keys, enumerate internal services, and pivot further into the SaaS infrastructure. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.

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.
