Security

All nginx security issues should be reported to F5SIRT@f5.com or via one of the methods listed here.

Patches are signed using one of the PGP public keys.

Special considerations

njs does not evaluate dynamic code and especially the code received from the network in any way. The only way to evaluate that code using njs is to configure the js_import directive in nginx. JavaScript code is loaded once during nginx start.

In nginx/njs threat model, JavaScript code is considered a trusted source in the same way as nginx.conf and sites certificates. What this means in practice:

• memory disclosure and other security issues triggered by JavaScript code modification are not considered security issues, but as ordinary bugs
• measures should be taking for protecting JavaScript code used by njs
• if no js_import directives are present in nginx.conf, nginx is safe from JavaScript-related vulnerabilities
