Stored XSS via unrestricted PUT uploads
Published Feb 11, 2024 · Updated Jun 16, 2025
Cross-site scripting in http-swagger before 1.2.6 allows remote attackers to execute JavaScript via uploaded HTML files. The WrapHandler passes non-document paths to a WebDAV handler that accepts PUT into an in-memory filesystem and later serves the content through GET. Exploitation requires another user to request the attacker-controlled file, allowing script execution in that user's browser.
