CVE-2026-32686

Uncontrolled Resource Consumption vulnerability in ericmj decimal allows unauthenticated remote Denial of Service. The decimal library does not bound the exponent on parsed input. Storing a decimal with a very large exponent (e.g. Decimal.new("1e1000000000")) is accepted without error. Subsequent calls to arithmetic functions (Decimal.add/2, Decimal.sub/2, Decimal.div/2), Decimal.to_string/2 with :normal or :xsd format, Decimal.to_integer/1, Decimal.round/3, or Decimal.compare/3 with a threshol
