Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The gin web framework (github.com/gin-gonic/gin) versions before 1.7.7 are vulnerable. When gin is exposed directly to the internet, a remote client can spoof its IP address by setting the X-Forwarded-For header. Upgrade to gin 1.7.7 or later.
