AI-suggested
The primary mitigation is to upgrade the 'send' library to version 0.19.0 or later, where the vulnerability is patched. Organizations should audit their dependencies to identify usage of affected versions. Additionally, implement strict input validation and output encoding on all user-supplied data, especially in URL redirects and file path parameters. Employ Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks. Regularly scan web applications with automated tools to detect XSS vulnerabilities. Educate developers on secure coding practices related to input handling and sanitization. Monitor web traffic for suspicious redirect patterns or script injections. Finally, maintain an up-to-date inventory of third-party libraries and apply security patches promptly.
Description
Send is a library for streaming files from the file system as a http response. Send passes untrusted user input to SendStream.redirect() which executes untrusted code. This issue is patched in send 0.19.0.
