CVE-2023-1895Network attack vector

Internal service access via unchecked REST URL

Published Jun 9, 2023 · Updated Apr 8, 2026

SSRF in Getwid – Gutenberg Blocks 1.8.3 and earlier allows remote authenticated users to send arbitrary GET requests through the server. The get_remote_content REST handler accepts a caller-supplied URL after only a read-capability check and retrieves it without validating the destination, returning JSON-formatted response data. Subscriber-level access is sufficient; reachable internal services can be queried or modified, and AWS EC2 IMDSv1 credentials can be disclosed.
