NVD Description

Note: Versions mentioned in the description apply only to the upstream hugo package and not the hugo package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Hugo versions from v0.162.0 before v0.166.0 contain a case-sensitive validation flaw in the security.http.urls IP-literal deny rule that allows attackers to bypass restrictions. Attackers can use mixed-case URL schemes in resources.GetRemote calls to fetch from restricted IP addresses like localhost.
