Commentary
The Hungarian word has two competing etymologies: Aikio (2022: 8) connects Hungarian has-ad to Finnish kiskoa: see UEW (s.v. kiśkɜ-) for other Uralic words that could reflect PU *kiśkV- (Hu kísál mentioned here has irregular long í and cannot be connected to the rest of the words). Aikio reconstructs (with a question mark) Proto-Uralic *kiśka-. This is an interesting idea, as PU *śk > Hu s would be a regular change, but more parallels would be needed for the change PU *i > Hu a (in *-a-stems) before the etymology can be accepted.
Metsäranta (2017: 220, footnote 15) suggests that Hungarian hasad, hasít could reflect PU *kačka- 'to bite'. This is phonologically the most plausible explanation so far.
The traditional Ugric etymology displays the correspondence Mansi *ć ~ Hu s which is rare in inherited vocabulary, and it is disputed whether this can reflect any Uralic phoneme regularly. Mansi short *a cannot reflect PU/Pug *a regularly, so the reconstruction given by UEW cannot be correct. PU *o could be reflected by Mansi *a in -ə-stems.
Conclusion
The Ugric etymology of hasad, hasít should be rejected, Metsäranta's Uralic etymology (PU *kačka-) is a plausible explanation.
