oapi-codegen 2.0.0 before 2.8.1 Code Injection via Non-String Enum Values

Impact

oapi-codegen versions 2.0.0 before 2.8.1 have a code injection vulnerability via non-string enum values in OpenAPI documents. Attackers can inject Go code, executing it when the generated package is built and imported. Affected versions are 2.0.0 to less than 2.8.1.

Original source description

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.
