CVE-2024-29180

CVE-2024-29180 is a path traversal vulnerability in webpack-dev-middleware, affecting versions prior to 7.1.0, 6.1.2, and 5.3.4, including projects using webpack-dev-server. An attacker can exploit insufficient URL validation by using percent-encoded characters (%2e, %2f) to access and exfiltrate any file on a developer's machine. This vulnerability carries a CVSS score of 7.5 (HIGH) due to its network-based attack vector and low attack complexity, potentially leading to high confidentiality impact without requiring user interaction. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
