CVE-2026-107449 - Heimdall Server-Side Request Forgery
CVE ID :CVE-2026-107449
Published : Oct. 8, 2026, 5:17 a.m. | 29 minutes ago
Description :linuxserver Heimdall through 2.8.3 applies its SafeUrlFetcher SSRF protection mechanism only to ItemController; the enhanced-application test and live-stats requests occur via SupportedApps::execute(), a GuzzleHttp client that lacks IP address restrictions. In some realistic installations, the POST /test_config (and GET /get_stats) endpoints are accessible through CSRF, and thus an unauthenticated attacker can force the server to send requests to arbitrary internal hosts and ports (including 169.254.169.254) and read a status/port oracle in addition to partial response data.
Severity: 3.4 | LOW
