Quick assessment
Affected
oapi-codegen oapi-codegen
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
oapi-codegen 2.0.0 至 2.8.1（不含 2.8.1）版本存在代码注入漏洞。攻击者可通过在整数、数字或布尔类型的 Schema 中提供非字面量（non-literal）的枚举项，注入 Go 代码。若攻击者能够控制 OpenAPI 文档，可构造一个枚举项，使 中的 代码块提前闭合，进而注入 函数。该恶意代码将在生成的包被构建并导入时执行。

Vulnerability Title
oapi-codegen 2.0.0 before 2.8.1 Code Injection via Non-String Enum Values
Source: CVE Program / CVE List V5
Vulnerability 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.
