CVE-2026-86118

MediumCVSS 4.3

Published: 05/09/2026(UTC)Translated: 05/09/2026(UTC)NVD NIST

Summary

gonic versions before 0.22.0 fail to validate administrator privileges in the startScan endpoint, allowing any authenticated user to trigger media library rescans. Attackers can repeatedly call the startScan endpoint to force CPU and I/O-intensive filesystem operations, causing denial of service on multi-user instances.

Risk Assessment

The risk includes server overload and service unavailability for other users, potentially leading to downtime and loss of productivity.

Recommendation

Update gonic to version 0.22.0 or later, which requires administrator privileges for startScan. Restrict access to the endpoint to trusted users only.

Other vulnerabilities in gonic
