CVE-2026-62308: CWE-918: Server-Side Request Forgery (SSRF) in Quenary tugtainer
CVE-2026-62308 is a critical Server-Side Request Forgery (SSRF) vulnerability in Quenary's Tugtainer, a self-hosted app for automating Docker container updates. Versions prior to 1.30.6 allow an authenticated user to make the backend server send HTTP requests to arbitrary URLs via the /settings/test_notification endpoint. This endpoint does not restrict protocols, hostnames, localhost, private IP ranges, or cloud metadata addresses, enabling blind SSRF attacks. The vulnerability has been patched in version 1.30.6.
AI Analysis
Technical Summary
Tugtainer versions before 1.30.6 contain an SSRF vulnerability (CWE-918) in the /settings/test_notification endpoint. Authenticated users can supply arbitrary URLs in the 'urls' field, which are passed directly to the Apprise notification service without validation or restrictions. This allows the backend server to make outbound HTTP requests to arbitrary destinations, including internal network resources and cloud metadata endpoints. The flaw is addressed by patching in version 1.30.6.
Potential Impact
An authenticated attacker can exploit this SSRF vulnerability to induce the server to send HTTP requests to arbitrary URLs, potentially accessing internal services, cloud metadata, or other restricted network resources. The CVSS 3.1 score of 9.1 indicates critical severity with high confidentiality impact, limited integrity impact, and high availability impact. This could lead to information disclosure and partial service disruption.
Mitigation Recommendations
Upgrade Tugtainer to version 1.30.6 or later, where this SSRF vulnerability has been patched. No other mitigation is required as the vendor has provided an official fix.
