Details

As written in the advisory (Markdown source, shown as plain text).

[CVE-2026-23947](https://github.com/advisories/GHSA-h526-wf6g-67jv) had an incomplete fix While the current [jsStringEscape](https://github.com/orval-labs/orval/blob/02211fc413524be340ba9ace866a2ef68845ca7c/packages/core/src/utils/string.ts#L227) function properly handles single quotes ('), double quotes (") and other characters, it fails to sanitize * and / characters. This allows attackers to break out of JavaScript comment blocks using */ sequences and inject arbitrary code into generated files. **Example:** ```yaml openapi: 3.0.4 info: title: Enum PoC version:
