### Description

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double-beta (0νββ) decay that has been able to reach the one-ton scale. The detector, located at the Laboratori Nazionali del Gran Sasso in Italy, consists of an array of 988 TeO$_{2}$ crystals arranged in a compact cylindrical structure of 19 towers. Following the completion of the detector construction in August 2016, CUORE began its first physics data run in 2017 at a base temperature of about 10 mK. Following multiple optimization campaigns in 2018, CUORE is currently in stable operating mode. In 2019, CUORE released its 2nd result of the search for 0νββ corresponding to a TeO$_{2}$ exposure of 372.5 kg∙yr and a median exclusion sensitivity to a $^{130}$Te 0νββ decay half-life of $1.7\times10^{25}$ yr. We find no evidence for 0νββ decay and set a 90% C.L. Bayesian lower limit of $3.2\times10^{25}$ yr on the $^{130}$Te 0νββ decay half-life. In this talk, we present the current status of CUORE's search for 0νββ, as well as review the detector performance. We finally give an update of the CUORE background model and the measurement of the $^{130}$Te two neutrino double-beta (2νββ) decay half-life.
