CVE-2026-30942: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in FlintSH FlareCVE-2026-30942 0 Flare is a Next.js-based, self-hostable file sharing platform that integrates with screenshot tools. Prior to 1.7.3, an authenticated path traversal vulnerability in /api/avatars/[filename] allows any logged-in user to read arbitrary files from within the application container. The filename URL parameter is passed to path.join() without sanitization, and getFileStream() performs no path validation, enabling %2F-encoded ../ sequences to escape the uploads/avatars/ directory and read any file accessible to the nextjs process under /app/. Authentication is enforced by Next.js middleware. However, on instances with open registration enabled (the default), any attacker can self-register and immediately exploit this. This vulnerability is fixed in 1.7.3. Join the discussion | CVE Database V5 | 03/10/2026, 16:44:10 UTC Added: 03/10/2026, 17:34:45 UTC |
