  We propose, as a novelty in the literature, the modelling of wormholes within
the particular case of the $f(R,T)$ gravity, namely $f(R,T)=R+\alpha
R^{2}+\lambda T$, with $R$ and $T$ being the Ricci scalar and trace of the
energy-momentum tensor, respectively, while $\alpha$ and $\lambda$ are
constants. Although such a functional form application can be found in the
literature, those concern to compact astrophysical objects, such that no
wormhole analysis has been done so far. The quadratic geometric and linear
material corrections of this theory make the matter content of the wormhole to
remarkably be able to obey the energy conditions.
