Summary

oapi-codegen from 2.0.0 before 2.8.1 contains a code injection flaw (CWE-94) in how it handles non-literal enum entries in integer, number, or boolean schemas. An attacker who controls an OpenAPI document can inject Go code that runs when the generated package is built and imported.

Description from the CNA

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.
