NewCVE-2026-12590 (opens in a new tab)How to fix?
Upgrade body-parser to version 1.20.6, 2.3.0 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to invalid limit option handling in normalizeOptions in lib/utils.js. An attacker can force oversized request bodies through by supplying an application configuration value for limit that parses to null, such as an unparseable string or NaN. When an app relies on limit to cap body size, the parser skips enforcement and accepts arbitrarily large payloads, driving excessive memory and CPU usage and degrading or crashing the service.
