| Package | Affected versions | Patched versions |
|---|---|---|
| hugo | ≥ 0.162.0, < 0.166.0 | 0.166.0 |
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.
