qutebrowser is an open source keyboard-focused browser with a minimal GUI.
Starting with qutebrowser v1.7.0, the Windows installer for qutebrowser
registers a qutebrowserurl:
URL handler. With certain applications,
opening a specially crafted qutebrowserurl:...
URL can lead to execution
of qutebrowser commands, which in turn allows arbitrary code execution via
commands such as :spawn
or :debug-pyeval
. Only Windows installs where
qutebrowser is registered as URL handler are affected. The issue has been
fixed in qutebrowser v2.4.0. The fix also adds additional hardening for
potential similar issues on Linux (by adding the new --untrusted-args flag
to the .desktop file), though no such vulnerabilities are known.
