  Recent results of the searches for Supersymmetry in final states with one or
two leptons at CMS are presented. Many Supersymmetry scenarios, including the
Constrained Minimal Supersymmetric extension of the Standard Model (CMSSM),
predict a substantial amount of events containing leptons, while the largest
fraction of Standard Model background events -- which are QCD interactions --
gets strongly reduced by requiring isolated leptons. The analyzed data was
taken in 2011 and corresponds to an integrated luminosity of approximately
$\mathcal{L} = 1\,\text{fb}^{-1}$. The center-of-mass energy of the pp
collisions was $\sqrt{s}=7\,\text{TeV}$.
