CVE-2021-27228 — An issue was discovered in Shinobi through ocean version 1

Critical CVSS 9.8

An issue was discovered in Shinobi through ocean version 1. lib/auth.js has Incorrect Access Control. Valid API Keys are held in an internal JS Object. Therefore an attacker can use JS Proto Method names (such as constructor or hasOwnProperty) to convince the System that the supplied API Key exists in the underlying JS object, and consequently achieve complete access to User/Admin/Super API functions, as demonstrated by a /super/constructor/accounts/list URI.

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
