The low mass star ASASSN-13db experienced an EXor outburst in 2013, whichidentified it as a Young Stellar Object (YSO). Then, from 2014 to 2017 it hadanother outburst, longer and more luminous than the earlier. We analyze theobservations of the second outburst, and compare it to eruptions ofIntermediate Luminosity Optical Transients (ILOTs). We show that the decline ofthe light curve is almost identical to that of the V838 Mon, a prototype of atype of ILOT known as Luminous Red Nova (LRN). This similarity becomesconspicuous when oscillations that are associated with rotation are filteredout from the light curve of ASASSN-13db. We suggest that the eruption was theresult of accretion of a proto-planet of a few Earth masses. The proto-planetwas shredded by tidal forces before it was accreted onto the YSO, releasinggravitational energy that powered the outburst for $\approx 800$ days, andended in a $\approx 55$ days decline phase. When the accretion material starteddepleting the accretion rate lowered and the eruption light curve declined foralmost two months. Then it exhausted completely, creating a sharp break in thelight curve. Another possibility is that the mass was a result of aninstability in the proto-planetary disk that lead to a large episode ofaccretion from an inner viscous disk. We find that the variation of thetemperature of the outburst is consistent with the surface temperature expectedfrom a depleted viscous accretion disk. The 2014-2017 outburst of ASASSN-13dbmay be the least energetic ILOT to have been discovered to date, with an energybudget of only $\approx 10^{42}$ erg.
