GHSA-GJXX-92W9-8V8F
Vulnerability from github – Published: 2026-03-27 19:58 – Updated: 2026-04-06 16:44Summary
The clerkFrontendApiProxy function in @clerk/backend is vulnerable to Server-Side Request Forgery (SSRF). An unauthenticated attacker can craft a request path that causes the proxy to send the application's Clerk-Secret-Key to an attacker-controlled server.
Affected packages
Only applications that have opted into the frontendApiProxy feature are affected. This feature is not enabled by default. Users of @clerk/nextjs are not affected due to how the framework handles repeated / in request paths.
| Package | Affected versions | Fixed version |
|---|---|---|
@clerk/backend |
>= 3.0.0, <= 3.2.2 |
3.2.3 |
@clerk/express |
>= 2.0.0, <= 2.0.6 |
2.0.7 |
@clerk/hono |
>= 0.1.0, <= 0.1.4 |
0.1.5 |
@clerk/fastify |
>= 3.1.0, <= 3.1.4 |
3.1.5 |
Search your codebase for the frontendApiProxy option. If none of the patterns below appear in your code, you are not affected.
@clerk/express
app.use(clerkMiddleware({ frontendApiProxy: { enabled: true } }));
@clerk/hono
app.use('*', clerkMiddleware({ frontendApiProxy: { enabled: true } }));
@clerk/fastify
fastify.register(clerkPlugin, { frontendApiProxy: { enabled: true } });
@clerk/backend
import { clerkFrontendApiProxy } from '@clerk/backend/proxy';
A quick way to check across your entire project:
grep -r "frontendApiProxy\|clerkFrontendApiProxy" .
If there are no matches, you are not using this feature.
Recommended actions
Clerk's internal logs show no evidence of users utilizing the built-in proxy with the impacted versions. Despite that, if you are on an impacted version and use the built-in proxy we recommend upgrading and rotating your Clerk Secret Key immediately.
- Upgrade to the patched version of
@clerk/backend(and@clerk/express,@clerk/hono, etc.) - Rotate your Clerk Secret Key after upgrading - if an attacker exploited this vulnerability, they may have captured your key. Rotate it in the Clerk Dashboard under API Keys. You should deploy your application with the updated key before revoking the existing key.
- Audit access logs for requests to your proxy endpoint (
/__clerk/by default) containing double slashes in the path.

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.
