CVE-2026-112237
An unauthenticated attacker can make the server send requests to arbitrary internal or external hosts.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
Description
The extension provides a public proxy endpoint that fetches a URL on behalf of the visitor. For one HTTP request method, the endpoint does not apply the authorization check that protects the other methods, so the URL it fetches is fully controlled by the requester. An unauthenticated attacker can make the server send requests to arbitrary internal or external hosts. The attacker receives the status code and selected response headers, which allows probing of internal hosts and ports. Response bodies are not disclosed.
