CVE detail

CVE-2026-44290

protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs allowed certain schema option paths to traverse through inherited object properties while applying options. A crafted protobuf schema or JSON descriptor could cause option handling to write to properties on global JavaScript constructors, corrupting process-wide built-in functionality. This vulnerability is fixed in 7.5.6 and 8.0.2.

  • Protocol Buffers schemas expose remote code execution riskCSO Online

    A widely used JavaScript implementation of Google’s Protocol Buffers format is placing too much trust in untrusted data, exposing affected applications to remote code execution and other attacks. Researchers at Cyera have disclosed six vulnerabilities affecting “protobuf.js,” all stemming from the library’s handling of schema and metadata. Attackers could exploit an input validation oversight to […]
