CWE-918

Server-Side Request Forgery (SSRF)

Title
SillyTavern: SSRF vulnerability in the CORS proxy middleware
Summary
SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to 1.18.0, corsProxyMiddleware forwards req.params.url directly into fetch(url, ...). It only blocks circular requests to its own host and does not enforce destination allowlist or private/loopback restrictions, enabling SSRF. This vulnerability is fixed in 1.18.0.

Title
python-utcp: SSRF via attacker-controlled OpenAPI servers[0].url in HTTP communication protocol
Summary
python-utcp is the python implementation of UTCP. Prior to 1.1.3, the utcp-http plugin is vulnerable to a blind Server-Side Request Forgery (SSRF) caused by a trust-boundary inconsistency between manual discovery and tool invocation. register_manual() validates the discovery URL against an HTTPS / loopback allowlist, but call_tool() and call_tool_streaming() reuse the resolved tool_call_template.url directly without revalidating, and the OpenAPI converter blindly trusts whatever servers[0].url an attacker-hosted spec declares. An attacker who hosts a malicious OpenAPI spec on a legitimate HTTPS endpoint can declare e.g. servers: [{ url: "http://127.0.0.1:9090" }] or servers: [{ url: "http://169.254.169.254" }]; the OpenAPI converter then produces tools whose URL points at internal services on the agent host. All three HTTP-class protocols (utcp_http.http, utcp_http.streamable_http, utcp_http.sse) shared the same gap. This vulnerability is fixed in 1.1.3.

n8n-MCP: Authenticated SSRF in n8n-mcp webhook and API client paths
Summary
n8n-MCP is an MCP server that provides AI assistants access to n8n node documentation, properties, and operations. From version 2.18.7 to before version 2.50.2, there is an authenticated server-side request forgery vulnerability affecting the webhook trigger tools, the n8n API client (N8N_API_URL), and per-request URLs supplied via the x-n8n-url header in multi-tenant HTTP mode. This issue has been patched in version 2.50.2.

Title
GuardDog: Blind GitHub URL rewrite in remote project scanning causes SSRF and `GH_TOKEN` exfiltration
Summary
GuardDog is a CLI tool to identify malicious PyPI packages. From 1.0.0 to 2.9.0, the programmatic remote project scanning path rewrites attacker-controlled repository URLs using a blind string replacement and then sends the caller's GitHub credentials with the resulting request. This allows an attacker who can influence the scanned repository URL to trigger SSRF and capture the GH_TOKEN used by GuardDog. This vulnerability is fixed in .

OpenClaw < 2026.4.20 - Server-Side Request Forgery via Browser CDP Profile Creation
Summary
OpenClaw before 2026.4.20 contains a server-side request forgery vulnerability in browser CDP profile creation that skips strict-mode SSRF policy checks. Attackers can create stored profiles pointing to private-network or metadata endpoints that bypass security policies and are later probed during normal profile status operations.

Title
Budibase: SSRF via trivial `.tar.gz` substring bypass in Plugin URL upload (`/api/plugin`)
Summary
Budibase is an open-source low-code platform. Prior to 3.35.10, the Plugin URL upload endpoint (POST /api/plugin) validates the submitted URL with a single substring check: url.includes(".tar.gz"). Any URL containing .tar.gz anywhere in the string — in the path, query string, or fragment — passes this check. The URL then proceeds directly to fetchWithBlacklist() with no further validation of host, scheme, or path. Standalone, this vulnerability is blocked by Budibase's default SSRF blacklist, which covers private IP ranges. But the URL validation layer itself is broken regardless, and it directly enables SSRF in two realistic situations: (1) when chained with the BLACKLIST_IPS bypass ([001]), where the blacklist is empty; and (2) when the plugin server follows HTTP redirects from an external URL to an internal target (the default node-fetch behavior with redirect: 'follow'). This vulnerability is fixed in 3.35.10.

Title
Karakeep has a SSRF Protection Bypass via Redirect Handling
Summary
Karakeep is a elf-hostable bookmark-everything app. A Server-Side Request Forgery (SSRF) protection bypass vulnerability was identified in versions prior to 0.32.0 affecting redirect-following processing components. Although the application implements protections intended to prevent requests toward internal/private network destinations, these protections could be bypassed through crafted HTTP redirect chains. By leveraging attacker-controlled redirects, an authenticated user could cause vulnerable application components to initiate requests toward internally reachable Docker network services accessible from the application environment. The issue affected multiple processing paths, including crawler-related functionality and video download processing flows. Version 0.32.0 contains a patch.

By leveraging attacker-controlled redirects, an authenticated user could cause vulnerable application components to initiate requests toward internally reachable Docker network services accessible from the application environment.

CVE-2026-45245 (GCVE-0-2026-45245)

Vulnerability from cvelistv5 – Published: 2026-05-18 19:00 – Updated: 2026-05-18 20:31 X_Open Source
VLAI
Title
Summarize < 0.15.1 Unauthorized Daemon Request via Untrusted Events
Summary
Summarize prior to 0.15.1 contains a vulnerability in the hover summary feature that allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links, causing the extension to make authenticated daemon requests using stored tokens without verifying event trustworthiness. Attackers can place local or private-network URLs behind hoverable links to route authenticated requests through the daemon, potentially accessing sensitive internal endpoints when users interact with attacker-controlled content.

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.
