We investigate the existence of vortex configurations in two gauged-$CP(2)$models extended via the inclusion of magnetic impurities. In particular, weconsider both the Maxwell-$CP(2)$ and the Chern-Simons-$CP(2)$ enlargedscenarios, separately. We choose a $CP(2)$-field configuration with a nulltopological charge not only in the simplest (free) case, but also when coupledto an Abelian gauge field. The implementation of theBogomol'nyi-Prasad-Sommerfield (BPS) formalism shows that the effective modelsfor such a configuration possess a self-dual structure which looks like thoseinherent to the gauged sigma models. Therefore, when the $CP(2)$ field iscoupled to the Maxwell term, the corresponding total energy possesses both awell-defined Bogomol'nyi bound and a quantized magnetic flux. Further, when the$CP(2)$ scenario is gauged with the Chern-Simons action, the total electriccharge is verified to be proportional to the quantized magnetic flux. Inaddition, the analysis verifies that the magnetic impurity contributes to theBPS potentials and appears in both the models' BPS equations. Next, weintroduce a Gaussian type impurity and solve the self-dual equations via afinite-difference scheme. The resulting solutions present a nonmonotonicbehavior that flips both the magnetic and electric fields. Finally, we discussthe topologically trivial solutions in the limit for which the impurity becomesa Dirac $\delta $-function.
