We investigate Color Flavor Locked (CFL) Strange Stars using the most basic de Rham–Gabadadze–Tolley massive gravity model, which explains the massive graviton in the absence of a ghost propagating mode. In the current study, the compact star model has been achieved by solving the field equations for a static, uncharged sphere (Li et al., in Phys Dark Universe 42: 101308, 2023). Here, we provide some analytical and numerical findings and examine the effects of the massive gravity and anisotropy characteristics on the structure of this stellar object. The modified Tolman–Oppenheimer–Volkoff equation is obtained by taking into account the hydrostatic equilibrium. In order to verify stability of the stellar object, we have taken into account the redshift function and adibatic index. Furthermore, it is observed that the model parameters have a substantial impact on the mass, radius, and compactness of the star object. Finally, our findings provide a possible structure of hypothetical super massive CFL strange stars, which may be placed in the lower “mass-gap” region $$2~M_{\odot }-5~M_{\odot }$$ 2 M ⊙ - 5 M ⊙ and remains stable without collapsing into a black hole corresponding to our considered model parameters.
