Description
The Visualizer WordPress plugin before 4.0.6 does not restrict a user-supplied URL to safe address ranges before fetching it server-side, allowing users with Contributor-level access and above to perform Server-Side Request Forgery against link-local instance-metadata endpoints. As the fetched response is returned in the reply, the attack is non-blind, enabling retrieval of cloud instance metadata (including IAM credentials) on cloud-hosted sites.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. A reference of the record is tagged as an exploit.
