description

Readest versions before 0.11.10 expose an unauthenticated OPDS proxy that can be induced to request attacker-selected URLs and return the resulting content. On deployments able to reach internal services, an attacker may access internal endpoints or cloud metadata through the application. Cloudflare Workers reduce access to private and link-local destinations, but the publicly reachable proxy remains exposed.

mitigation

Upgrade Readest to version 0.11.10 or later. Until upgraded, restrict public access to the OPDS proxy endpoint and limit the application's outbound network access.
