Subject: Re: MantisBT weakened CSP when using bundled Gravatar plugin
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
> MantisBT 1.3.0-rc.2 introduced a new bundled plugin to handle display of
> users' avatars using Gravatar.
>
> Instead of adding the Gravatar web site to the list of allowed image
> sources in MantisBT's Content Security Policy, the plugin was replacing
> the whole policy by:
>
> img-src 'self' http://www.gravatar.com/
>
> instead of the more strict default one of:
>
> default-src 'self'; frame-ancestors 'none'; style-src 'self';
> script-src 'self'
>
> Relaxed policy allows execution of remote and inline scripts, e.g.
> potentially enabling XSS attacks.
