AI Summary

Researchers at Cyera identified six vulnerabilities in the JavaScript implementation of Google’s Protocol Buffers, known as protobuf.js. The flaws arise from the library’s excessive trust in untrusted data, particularly in how it processes schema and metadata. An attacker could exploit an input‑validation oversight to inject malicious data, potentially leading to remote code execution or other attacks that alter an application’s behavior. The discovery highlights the risk of using protobuf.js in environments where untrusted data is parsed.
