Access restriction bypass |

| Description |

WebExtensions in Firefox < 51 could use the mozAddonManager API by modifying the CSP headers on sites with the appropriate permissions and then using host requests to redirect script loads to a malicious site. This allows a malicious extension to then install additional extensions without explicit user permission. |
