Summary of the CKM 2023 Working Group on $V_{ub}$, $V_{cb}$ and semileptonic/leptonic B decays including $\tau$

This work summarizes recent results, both theoretical and experimental, in $B$-meson leptonic and semileptonic decays and metrology of $V_{ub}$ and $V_{cb}$, which were presented at the CKM 2023 workshop. We place these results in context and discuss future prospects in the field.
