AI-suggested
The primary mitigation is to upgrade Wallos installations to version 4.7.0 or later, which patches the SSRF vulnerabilities across all affected endpoints. Organizations should audit and restrict access to internal network services and cloud metadata endpoints from application servers, implementing network segmentation and firewall rules to limit outbound requests. Additionally, review and harden authentication mechanisms to prevent unauthorized access to the application. Implement strict input validation and URL allowlisting on any parameters that trigger server-side requests. Monitoring and logging outbound requests from the application can help detect anomalous SSRF attempts. For cloud environments, enforce the use of IMDSv2 or equivalent metadata service protections to reduce risk from SSRF attacks. Regularly review and update dependencies and apply security patches promptly.
Description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the patch introduced in commit e8a513591 (CVE-2026-30840) added SSRF protection to notification test endpoints but left three additional attack surfaces unprotected: the AI Ollama host parameter, the AI recommendations endpoint, and the notification cron job. An authenticated user can reach internal network services, cloud metadata endpoints (AWS IMDSv1, GCP, Azure IMDS), or localhost-bound services by supplying a crafted URL to any of these endpoints. This issue has been patched in version 4.7.0.
