Fedora 44 : gum (2026-10cf6ce616)

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-10cf6ce616 advisory. Update vendored goldmark to 1.7.17 to resolve CVE-2026-5160. Tenable has extracted the preceding description block directly from the Fedora security advisory...

Versions of the package github.com/yuin/goldmark/renderer/html before 1.7.17 are vulnerable to Cross-site Scripting (XSS) due to improper ordering of URL validation and normalization. The renderer validates link destinations using a prefix-based check (IsDangerousURL) before resolving HTML entities.
