Description

The remote Redhat Enterprise Linux 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2026:69099 advisory.

yggdrasil-worker-package-manager is a simple package manager yggd worker.

* net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution (CVE-2026-56860)
