Security Features Home Extensions Ecosystem

CSP tells the browser where it’s OK to load resources from.

This can help prevent certain attacks, such as XSS. CSP disables the ability to load malicious scripts and styles.

Like CORS, CSP is handled through a ruleset. This allows parts of a site to use different policies.

Note that previous versions of Kvarn (before v0.4.0), the new method meant empty. You should probably always use default. See the example below.

In situations where you want a clean slate, use the empty method. Then, I’d recommend setting a catch-all method (using path *).

Reverse proxy CSP getting overridden

This is intended behaviour to reduce risks of XSS.

You can disable CSP by adding a empty ruleset:



let mut extensions = Extensions::new();
