Next.js Server-Side Request Forgery in Server Actions
Impact
A Server-Side Request Forgery (SSRF) vulnerability was identified in Next.js Server Actions by security researchers at Assetnote. If the Host header is modified, and the below conditions are also met, an attacker may be able to make requests that appear to be originating from the Next.js application server itself.
Prerequisites
Next.js (<14.1.1) is running in a self-hosted manner.
The Next.js application makes use of Server Actions.
The Server Action performs a redire
jsonwebtoken unrestricted key type could lead to legacy keys usage
Overview
Versions <=8.5.1 of jsonwebtoken library could be misconfigured so that legacy, insecure key types are used for signature verification. For example, DSA keys could be used with the RS256 algorithm.
Am I affected?
You are affected if you are using an algorithm and a key type other than the combinations mentioned below
| Key type | algorithm |
|----------|------------------------------------------|
| ec | ES256, ES384, ES512
