CVE-2024-10491: Preload arbitrary resources by injecting additional `Link` headers

First published: Tue Oct 29 2024(Updated: )

A vulnerability has been identified in the Express response.links function, allowing for arbitrary resource injection in the Link header when unsanitized data is used. The issue arises from improper sanitization in `Link` header values, which can allow a combination of characters like `,`, `;`, and `<>` to preload malicious resources. This vulnerability is especially relevant for dynamic parameters.
