GHSA-88C3-G468-4JGG

Vulnerability from github – Published: 2026-05-20 03:31 – Updated: 2026-05-20 03:31
VLAI
Details

The Nexa Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in versions up to and including 1.1.1. This is due to the import_demo() function accepting a user-supplied URL in the demo_json_file POST parameter and passing it directly to wp_remote_get() without any URL validation or restriction against internal or private network destinations. The nexa_blocks_nonce required for the AJAX action is publicly exposed in the HTML source of any frontend page where the plugin is active via wp_localize_script on the enqueue_block_assets hook, effectively making the nonce available to all visitors and bypassing any intended authentication barrier. This makes it possible for unauthenticated attackers to make server-side HTTP requests to arbitrary internal or external destinations, potentially exposing internal services, cloud metadata endpoints such as the AWS instance metadata service, localhost services, and other resources not intended to be publicly accessible. A secondary SSRF vector also exists whereby image URLs extracted from the attacker-controlled JSON response are subsequently fetched via a second wp_remote_get() call, allowing chained exploitation through a crafted JSON payload.

GHSA-88GM-J2WX-58H6

Vulnerability from github – Published: 2026-04-23 21:52 – Updated: 2026-04-27 16:42
VLAI
Summary
Cloudflare has SSRF via redirect following through its image-binding-transform endpoint (incomplete fix for GHSA-qpr4)
Details

Summary

The fetch() call for remote images in packages/integrations/cloudflare/src/utils/image-binding-transform.ts (line 28) uses the default redirect: 'follow' behavior. This allows the Cloudflare Worker to follow HTTP redirects to arbitrary URLs, bypassing the isRemoteAllowed() domain allowlist check which only validates the initial URL.

All three other image fetch paths in the codebase correctly use { redirect: 'manual' }. This is an incomplete fix for GHSA-qpr4-c339-7vq8.

Confirmed on HEAD.

Root Cause

image-binding-transform.ts line 28:

const content = await (isRemotePath(href) ? fetch(imageSrc) : assets.fetch(imageSrc));

Missing { redirect: 'manual' }. The three protected paths:

// image-passthrough-endpoint.ts:23
response = await fetch(href, { redirect: 'manual' });

// assets/endpoint/shared.ts:11
const res = await fetch(src, { redirect: 'manual' });

// assets/utils/remoteProbe.ts:53
const response = await fetch(url, { redirect: 'manual' });

PoC

Demonstrated with Node.js that fetch() without redirect: 'manual' follows 302 redirects to arbitrary destinations:

# Server A (allowed domain) returns 302 → Server B (internal)
fetch('http://allowed:19741/img.jpg')                        → follows 302 → hits http://internal:19742/secret
fetch('http://allowed:19741/img.jpg', {redirect:'manual'})   → returns 302, internal server NOT hit

Attack path: attacker finds an open redirect on an allowed domain, crafts /_image?href=https://allowed-cdn.com/redirect?url=http://internal-service/, and the Worker follows the redirect to the unauthorized destination.

Impact

Bypasses the image.domains and image.remotePatterns allowlist for the default Cloudflare image service (cloudflare-binding). Enables blind SSRF to domains not in the allowlist. Same vulnerability class as GHSA-qpr4-c339-7vq8 (HIGH) which fixed the passthrough endpoint but missed this one.

Suggested Fix

const content = await (isRemotePath(href) ? fetch(imageSrc, { redirect: 'manual' }) : assets.fetch(imageSrc));

Vulnerability from github – Published: 2026-09-27 18:30 – Updated: 2026-09-27 18:30
VLAI
Details

python-utcp (pip package utcp-http) before 1.1.12 does not verify whether tool URLs declared in a hand-written UTCP manual point at the agent's own loopback interface when that manual is discovered from a remote, non-loopback origin. Because ensure_secure_url intentionally permits loopback HTTP for local development and native manuals bypassed the loopback check performed by the OpenAPI converter, an attacker who can serve a UTCP manual that a victim registers can cause the client to issue requests to services bound only to 127.0.0.1 on the victim host and have the response bodies returned to the caller (server-side request forgery). The http, sse and streamable_http protocols are all affected. Reach is limited to loopback, and exploitation further requires a loopback service that answers unauthenticated requests with useful data. Fixed in utcp-http 1.1.12, which rejects manuals fetched from a non-loopback origin that declare loopback tool URLs, keyed off the final post-redirect discovery URL.

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.
