CVE-2020-11054

Advisory

Qutebrowser 1.11.1 includes a fix for CVE-2020-11054: After a certificate error was overridden by the user, qutebrowser displays the URL as yellow ('colors.statusbar.url.warn.fg'). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green ('colors.statusbar.url.success_https'). While the user already has seen a certificate error prompt at this point (or set 'content.ssl_strict' to 'false' which is not recommended), this could still provide a false sense of security.

- **CVE-2020-11054**: After a certificate error was overridden by the user, qutebrowser displays the URL as yellow (`colors.statusbar.url.warn.fg`). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green (`colors.statusbar.url.success_https`). While the user already has seen a certificate error prompt at this point (or set `content.ssl_strict` to `false` which is not recommended), this could still provide a false sense of security. This is now fixed.
