  We revisit the viability of the CMSSM, searching for regions of parameter
space that yield a neutralino dark matter density compatible with Planck
measurements, as well as LHC constraints including sparticle searches and the
mass of the Higgs boson, recent direct limits on spin-independent and
-dependent dark matter scattering from the LUX-ZEPLIN (LZ) experiment, the
indirect constraints from Fermi-LAT and H.E.S.S. on dark matter annihilations
to photons in dwarf spheroidal galaxies and the Galactic Centre, and the
IceCube limits on muons from annihilations to neutrinos in the Sun. For
representative values of $\tan \beta$ and $A_0$ we map in detail the
Planck-compatible strips in CMSSM parameter planes, which exhibit multiple
distinctive features for large $\tan \beta$, $A_0 = 0$ and $\mu > 0$, and
identify portions of the strips that survive all the phenomenological
constraints. We find that the most powerful constraint is that from $m_h$,
followed by the LZ limit on spin-independent scattering, whereas sparticle
searches at the LHC and indirect dark matter searches are less restrictive.
Most of the surviving CMSSM parameter space features a Higgsino-like dark
matter particle with a mass $\sim 1000-1100$ GeV, which could best be probed
with future direct searches for dark matter scattering.
