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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-94"],"vendors":[],"products":[],"references":[{"url":"https://github.com/oapi-codegen/oapi-codegen/blob/v2.0.0/pkg/codegen/templates/constants.tmpl#L12","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/blob/v2.8.0/pkg/codegen/templates/constants.tmpl#L16","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/commit/068f1bcd16e4724c72d78d6774008a877b8297b1","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/pull/2626","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/releases/tag/v2.8.1","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/security/advisories/GHSA-g2vv-83pm-v2hc","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/security/advisories/GHSA-xrqw-w576-xgj2","tags":[]},{"url":"https://www.vulncheck.com/advisories/oapi-codegen-2.0.0-before-2.8.1-code-injection-via-non-string-enum-values","tags":[]}],"exploitRefs":[{"url":"https://github.com/oapi-codegen/oapi-codegen/blob/v2.0.0/pkg/codegen/templates/constants.tmpl#L12","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/blob/v2.8.0/pkg/codegen/templates/constants.tmpl#L16","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/commit/068f1bcd16e4724c72d78d6774008a877b8297b1","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/pull/2626","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/releases/tag/v2.8.1","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/security/advisories/GHSA-g2vv-83pm-v2hc","tags":[]},{"url":"https://github.com/oapi-codegen/oapi-codegen/security/advisories/GHSA-xrqw-w576-xgj2","tags":[]}],"hasPoc":true,"ai":null}
