Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Gitea before 1.27.0 lets repository migration URL validation be bypassed when a hostname resolves to both allowed and blocked IP addresses. An authenticated user who can create repository migrations can make the server clone internal-only Git services and import their contents. Upgrade to Gitea 1.27.0.
