"details" : "# Description\n\nAfter 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.\n\n# Affected versions and patches\n\nAll versions of qutebrowser are believed to be affected, though versions before v0.11.x couldn't be tested.\n\nThe issue is fixed in qutebrowser v1.11.1 (pending release) and v1.12.0 (unreleased). Backported patches for older versions are available, but no further releases are planned.\n\n# Mitigation\n\nIf you are unable to upgrade:\n\n- Treat any host with a certificate exception as insecure, ignoring the URL color\n- Or set `content.ssl_strict` to `True` (instead of `'ask'`), preventing certificate exceptions\n\n# References\n\n- qutebrowser issue: https://github.com/qutebrowser/qutebrowser/issues/5403\n- Fix (master branch): https://github.com/qutebrowser/qutebrowser/commit/021ab572a319ca3db5907a33a59774f502b3b975\n- Related issue for KDE Falkon: https://bugs.kde.org/show_bug.cgi?id=420902\n- Related issue for eric6 Web Browser: https://tracker.die-offenbachs.homelinux.org/eric/issue328 (fixed in eric6 20.6)",
