Directory Traversal

Overview org.webjars.npm:nitropack is a Build and Deploy Universal JavaScript Servers Affected versions of this package are vulnerable to Directory Traversal via the routeRules function. An attacker can access files or endpoints outside the intended proxy scope by sending specially crafted URLs...

CVE-2026-6321

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications...

CVE-2026-6414

A flaw was found in @fastify/static. A remote attacker can exploit this vulnerability by sending specially crafted requests that include percent-encoded path separators. This mismatch in how @fastify/static decodes these separators compared to the Fastify router allows the attacker to bypass...
