CVE-2024-29896: Astro-Shield's Content-Security-Policy header generation in middleware could be compromised by malicious injections
First published: Thu Mar 28 2024(Updated: )
### Impact When the following conditions are met: - Automated CSP headers generation for SSR content is enabled - The web application serves content that can be partially controlled by external users Then it is possible that the CSP headers generation feature might be "allow-listing" malicious injected resources like inlined JS, or references to external malicious scripts. ### Patches Available in version 1.3.0 . ### Workarounds - Do not enable CSP headers generation. - Use it only for dynamically generated content that cannot be controlled by external users in any way. ### References _Are there any links users can visit to find out more?_
