Machine-written summary

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

Soft Serve, the Go package github.com/charmbracelet/soft-serve, is affected in versions before 0.11.1 by a server-side request forgery flaw in its webhooks feature. The source gives few details beyond this, so it is unclear what access an attacker needs. Upgrade to version 0.11.1 or later, which contains the fix.
