  The main objective of this work is to study the structure, composition, and
oscillation modes of color superconducting quark stars with intense magnetic
fields. We adopted the MIT bag model within the color superconductivity CFL
framework, and we included the effects of strong magnetic fields to construct
the equation of state of stable quark matter. We calculated observable
quantities, such as the mass, radius, frequency, and damping time of the
oscillation fundamental $f$ mode of quark stars, taking into account current
astrophysical constraints. The results obtained show that color superconducting
magnetized quark stars satisfy the constraints imposed by the observations of
massive pulsars and gravitational wave events. Furthermore, the quantities
associated with the oscillation $f$ mode of these objects fit the universal
relationships for compact objects. In the context of the new multi-messenger
gravitational wave astronomy era and the future asteroseismology of neutron
stars, we hope that our results contribute to the understanding of the behavior
of dense matter and compact objects.
