How many vulnerabilities does transformers have?

56 vulnerabilities are recorded for transformers in the PyPI ecosystem: 1 critical, 8 high, 13 medium and 2 low, plus 32 not yet rated. The ledger on this page lists the same counts next to the date of the most recent disclosure.

How often are new transformers vulnerabilities disclosed?
