Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Gitea versions before 1.25.5 are vulnerable, because git grep searches have no enforced timeout. An attacker who can run repository searches can submit expensive searches that consume server resources. Upgrade to Gitea 1.25.5 or later. The source gives few details about the required access level.
