Title
NewsBlur < 14.5.0 - Server-Side Request Forgery via add_url Endpoint
Summary
NewsBlur before version 14.5.0 contains a server-side request forgery vulnerability in the add_url endpoint that allows authenticated users to make arbitrary server requests to internal networks by failing to filter private IP addresses. Attackers can exploit this to access localhost services and cloud metadata endpoints, enabling internal network scanning and sensitive data exfiltration.

Title
Huly Platform - Server-Side Request Forgery via /import Endpoint
Summary
Huly Platform through 0.7.423, fixed in commit 68cbf8a contains an authenticated server-side request forgery vulnerability in the /import endpoint of front pod that allows workspace users to make arbitrary server requests. Attackers can exploit this by supplying malicious URLs to fetch internal services, exfiltrate responses, and replay credentials against backend systems.

CVE-2026-56676 (GCVE-0-2026-56676)

Title
9router: Image prefetch DNS rebinding allows SSRF to internal services
Summary
9Router is an AI router & token saver. Prior to 0.5.2, 9router validates image URLs by resolving the host before fetching, but open-sse/translator/concerns/image.js performs the later server-side image fetch with a separate DNS resolution. An authenticated attacker with access to the LLM proxy can use a vision-capable model and an attacker-controlled DNS name that first resolves to a public IP and then rebinds to an internal address, allowing server-side requests to internal-only HTTP services. This issue is fixed in version 0.5.2.

CVE-2026-56663 (GCVE-0-2026-56663)

Title
AutoGPT: SSRF-to-RCE Chain in `SendWebRequestBlock` via IP validation bypass and internal `pg-meta` access
Summary
AutoGPT is a workflow automation platform for creating, deploying, and managing continuous artificial intelligence agents. Prior to 0.6.52, an authenticated user can bypass the SSRF / private-IP protections in SendWebRequestBlock and reach internal network services. _is_ip_blocked() in backend/backend/util/request.py does not normalize IPv4-mapped IPv6 addresses before checking resolved IPs against the blocked IPv4 ranges, and does not block special-use ranges such as 100.64.0.0/10 (CGNAT, RFC 6598). A hostname that resolves to an IPv4-mapped IPv6 address therefore passes validation and the request reaches the embedded internal IPv4 endpoint. This affects all AutoGPT Platform deployments. This vulnerability is fixed in 0.6.52.

Title
Open WebUI - Server-Side Request Forgery via Location Redirect in /api/v1/retrieval/process/web
Summary
Open WebUI before 0.6.27 contains a server-side request forgery vulnerability in the /api/v1/retrieval/process/web endpoint that allows authenticated users to bypass SSRF protections. Attackers can manipulate URL parameters with location redirect headers to access internal services and potentially execute commands via instance secrets.

Title
n8n - Credential Exfiltration via Allowed HTTP Request Domains Bypass in Dynamic Node Parameters Endpoint
Summary
n8n before 2.20.0 contains a credential exfiltration vulnerability in the POST /rest/dynamic-node-parameters/options endpoint that allows authenticated users to bypass Allowed HTTP Request Domains restrictions. Attackers with credential access can cause the n8n server to issue HTTP requests with credentials to unauthorized hosts, exfiltrating sensitive authentication data.

Title
AVideo - Server-Side Request Forgery in Live/test.php via statsURL Parameter
Summary
AVideo through version 27.0 contains a server-side request forgery vulnerability in plugin/Live/test.php that allows authenticated administrators to read arbitrary URLs via the statsURL parameter, which lacks isSSRFSafeURL() validation and accepts requests to private IP ranges and cloud metadata endpoints. Attackers can exploit this by crafting requests to internal services, cloud metadata endpoints like 169.254.169.254, and localhost to retrieve sensitive information including IAM credentials, internal service responses, and network configuration details.

Title
Nitter - Server-Side Request Forgery in /video Media Proxy Endpoint
Summary
Nitter's /video media proxy endpoint fails to validate target URLs against Twitter/X domains and uses a hardcoded default HMAC key, allowing unauthenticated attackers to compute valid HMACs for arbitrary URLs. Attackers can retrieve HTTP responses from any host reachable by the server, including cloud metadata services and internal network resources.

Title
Flowise - Server-Side Request Forgery via Execute Flow Base URL
Summary
Flowise before 3.1.0 contains a server-side request forgery vulnerability in the Execute Flow node that allows attackers to bypass security validation by providing intranet addresses through the base URL field. Attackers can initiate HTTP requests to internal network addresses, access cloud metadata, and enumerate internal services by exploiting the missing secureFetch verification in httpSecurity.ts.

Title
Crawl4AI - Server-Side Request Forgery via Direct Crawl Endpoints
Summary
Crawl4AI before 0.8.7 contains a server-side request forgery vulnerability in the /crawl, /crawl/stream, /md, and /llm endpoints that fetch arbitrary user-supplied URLs without validation. Unauthenticated attackers can bypass the internal-address blocklist using IPv6-mapped IPv4 addresses to reach internal services and cloud metadata endpoints.

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.
