CVE-2026-119027

oapi-codegen 2.5.0 before 2.8.1 contains a code injection vulnerability that allows attackers to inject Go code by supplying a crafted servers[].x-go-name value emitted unescaped by the server-urls template. Attackers who control an OpenAPI document can define an injected func init() that executes when the victim builds and imports the generated package.
