oapi-codegen 2.0.0 before 2.8.1 contains a code injection vulnerability that allows attackers to inject Go code by supplying non-literal enum entries in integer, number, or boolean schemas. Attackers controlling an OpenAPI document can craft an enum entry that closes the const block in constants.tmpl and injects a func init(), executing code when the generated package is built and imported.
