NewCVE-2026-44294 (opens in a new tab)How to fix?
Upgrade protobufjs to version 7.5.6, 8.0.2 or higher.
Overview
protobufjs is a protocol buffer for JavaScript (& TypeScript).
Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions when handling field names containing control characters in schemas or JSON descriptors. An attacker can cause runtime errors and disrupt application functionality by supplying crafted schemas or descriptors that trigger syntax errors during code generation.
Note: This is only exploitable if the application loads untrusted schemas or descriptors and performs operations that trigger code generation, such as encode, decode, verify, fromObject, or toObject.
