Machine-written summary

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

GHSA-rjwr-m7qx-3fjr affects the oapi-codegen Go module github.com/oapi-codegen/oapi-codegen/v2 before 2.7.1, and the fix is in 2.7.1. An attacker who can supply or influence the OpenAPI document (its servers description field, which can contain newlines) can get arbitrary Go declarations emitted into generated code, leading to code execution when that code is built or run. Upgrade to 2.7.1 or later, and review generated code before running it.
