Prior to version 1.20.3, authenticated users with the `asset:import` permission can trigger server-side HTTP requests to attacker-controlled URLs through the Asset CSV Content Import feature. The `imageUrl` validation logic can be bypassed through multiple techniques, including image-extension suffixes, image-related path keywords, domain substring matching, and redirect chains. After validation, the server performs an unrestricted `fetch()` request to the supplied URL. This results in a Server-Side Request Forgery (SSRF) vulnerability that allows attackers to reach internal network services, cloud metadata endpoints, and arbitrary external hosts from the application&#8217;s network context. Additionally, response bodies are fully buffered before size validation, creating a potential memory exhaustion vector. Version 1.20.3 patches the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shelf is a platform for tracking physical assets.
