Summary
Spring AI: Insufficient Validation causes SSRF when processing multimodal messages with user-supplied URLs
Details

Spring AI's spring-ai-bedrock-converse contains a Server-Side Request Forgery (SSRF) vulnerability in BedrockProxyChatModel when processing multimodal messages that include user-supplied media URLs. Insufficient validation of those URLs allows an attacker to induce the server to issue HTTP requests to unintended internal or external destinations.

This issue affects Spring AI: from 1.0.0 before 1.0.5, from 1.1.0 before 1.1.4.

Vulnerability from github – Published: 2026-06-24 09:30 – Updated: 2026-06-24 09:30
VLAI
Details

The Kargo Takip plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.2 via the 'api_url' parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. The script echoes internal API response data (specifically the value of any 'auth' key in a JSON response body) verbatim back to the attacker's browser, enabling direct exfiltration of responses from internal services such as cloud instance metadata endpoints.

Summary
Server-Side Request Forgery in @uppy/companion
Details

Versions of @uppy/companion prior to 1.9.3 are vulnerable to Server-Side Request Forgery (SSRF). The get route passes the user-controlled variable req.body.url to a GET request without sanitizing the value. This allows attackers to inject arbitrary URLs and make GET requests on behalf of the server.

Recommendation

Upgrade to version 1.9.3 or later.

Summary
Aimeos Pagible CMS vulnerable to Server Side Request Forgery (SSRF) via DNS rebinding in admin proxy
Details

Summary

The administrative proxy route (cmsproxy) in Aimeos Pagible CMS is vulnerable to a Server-Side Request Forgery (SSRF) attack via DNS Rebinding. A Time-of-Check to Time-of-Use (TOCTOU) race condition exists between the URL validation phase and the actual HTTP request phase, allowing attackers to access internal network resources and cloud metadata endpoints.

Details

Before executing an HTTP request to fetch external content, the AdminController::proxy controller validates the target URL using \Aimeos\Cms\Utils::isValidUrl($url). This function performs a DNS query to verify that the hostname does not resolve to private or reserved IP ranges (e.g., 127.0.0.1, 10.0.0.0/8, 169.254.169.254).

If the validation passes, the application proceeds to the "Use" phase, invoking Guzzle/cURL to send the request. However, Guzzle performs a second DNS lookup to establish the socket connection.

An attacker can exploit this by setting up a malicious DNS server for a domain they control and configuring it with a TTL of 0. 1. During the validation "Check", the DNS server returns a safe, public IP. 2. During the Guzzle "Use", the DNS server returns an internal/private IP.

### POC 1. Attacker registers rebound.test.com with a custom nameserver. 2. Attacker generates a valid proxy token (assuming basic authenticated access). 3. Attacker requests/cmsproxy?url=http://rebound.test.com. 4.isValidUrlchecksrebound.test.com. DNS returns8.8.8.8. Validation passes. 5. Guzzle requestshttp://rebound.test.com. DNS returns169.254.169.254`. 6. The CMS fetches AWS Instance Metadata and returns it to the attacker.

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.
