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/2M), Decimal.to_string/2M with :normalM or :xsdM format, Decimal.to_integer/1M, Decimal.round/3M, or Decimal.compare/3M with a threshold allocate memory proportional to the exponent value, which can exhaust available memory and crash the BEAM VM.\n\nAny application that accepts user-supplied decimal input and subsequently performs arithmetic, rounding, conversion to integer, or string formatting on it is exposed. A single malicious request is sufficient to cause an out-of-memory crash.\n\nThis issue affects decimal: from 0.1.0 before 3.0.0.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-400"],"references":["https://cna.erlef.org/cves/CVE-2026-32686.html","https://github.com/ericmj/decimal/commit/6a523f3a73b8c9974540e21c7aa88f1258bb35ae","https://github.com/ericmj/decimal/commit/bc11f4a2b6fb61fc1360a0ab4e79141bba918841","https://github.com/ericmj/decimal/security/advisories/GHSA-rhv4-8758-jx7v","https://osv.dev/vulnerability/EEF-CVE-2026-32686"],"products":[],"source":"nvd","synced_at":"2026-10-26T20:34:58.897451322+00:00"},"epss":{"cve":"CVE-2026-32686","score":0.00484,"percentile":0.41454,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
