WebKaplan-Meier estimator. Another known estimator of the baseline function is a kernel estimator, introduced by Ramlau-Hansen (1983a; 1983b), which is obtained by smoothing the Breslow estimator of the cumulative baseline function. Guilloux et al., (2016) introduced an adaptive kernel estimation of the baseline http://dutiosc.twi.tudelft.nl/~lopuhaa/homepage/paper1final.pdf

Yes, it probably shouldn't be used as an estimate of hazard, and as Elvis points out the rest of the paper notes that Breslow didn't really intend it for that purpose.
