    CVE-2017-5389

    Published: 11 Jun 2018Last Modified: 10 Mar 2026

    Summary:

    Details: WebExtensions 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. This vulnerability affects Firefox < 51.
