oapi-codegen 2.0.0 版前 2.8.1 的非字串 Enum 值導致 Go 程式碼注入漏洞
CVE-2026-119028 - oapi-codegen 2.0.0 before 2.8.1 Code Injection via Non-String Enum Values
導語：oapi-codegen 2.0.0 版前 2.8.1 之非字串 Enum 值導致 Go 程式碼注入漏洞，允許攻擊者透過 OpenAPI 檔案注入任意 Go 程式碼。
此漏洞允許攻擊者透過 OpenAPI 檔案注入 Go 程式碼，影響多版本 oapi-codegen，提醒開發者即時升級或驗證生成程式碼。
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.

The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 83251b91-4cc7-4094-a5c7-464a1b83ea10 | ||||
| CVSS 3.1 | HIGH | MITRE-CVE | ||||
| CVSS 4.0 | HIGH | 83251b91-4cc7-4094-a5c7-464a1b83ea10 |
Update oapi-codegen to version 2.8.1 or later to fix a code injection vulnerability.
- Update oapi-codegen to version 2.8.1 or later.
- Validate generated code for suspicious entries.
- Review OpenAPI documents for malicious enum entries.
We scan GitHub repositories to detect new proof-of-concept exploits. Following list is a collection of public exploits and proof-of-concepts, which have been published on GitHub (sorted by the most recently updated).
Results are limited to the first 15 repositories due to potential performance issues.
