The most recent measurements of Higgs boson production cross-sections and couplings in the $WW$ decay channel will be presented. The measurements make use of the Run 2 LHC data collected by the CMS detector in proton-proton collisions at a center-of-mass energy of 13 TeV. The presented results cover the $ggH$, VBF, $WH$ and $ZH$ Higgs boson production mechanisms and span a large variety of final states with 2, 3 and 4 charged leptons. The measurement of Higgs boson production cross-sections in the Simplified Template Cross-Sections (STXS) framework will also be presented. The higher integrated luminosity and the newly developed analysis techniques allowed an unprecedented precision of the cross-sections and couplings measurements, with a significant improvement with respect to the latest published results.
