CVE-2024-45296 is a high-severity vulnerability in the path-to-regexp library, a widely used Node.js utility for converting route patterns like /user/:id into regular expressions. Under common route configurations, the library can generate regex patterns that trigger catastrophic backtracking, leading to excessive CPU consumption. This flaw creates a low-complexity Denial-of-Service (DoS) vector, allowing an attacker to freeze Node.js servers by sending specially crafted requests. The vulnerability affects applications relying on path-to-regexp for routing, including many popular frameworks. Discussions on WindowsForum cover the technical details, impact, and mitigation strategies for CVE-2024-45296, emphasizing the need for prompt patching to prevent service disruption.
