Viewing Security Vulnerabilities


The image vulnerabilities command can be used to return a list of vulnerabilities found in the container image.

# anchorectl image vulnerabilities INPUT_IMAGE -t VULN_TYPE

The INPUT_IMAGE can be specified in one of the following formats:

  • Image Digest
  • Image ID
  • registry/repo:tag

The VULN_TYPE currently supports:

  • os: Vulnerabilities against operating system packages (RPM, DPKG, APK, etc.)
  • non-os: Vulnerabilities against language packages (NPM, GEM, Java Archive (jar, war, ear), Python PIP, .NET NuGet, etc.)
  • all: Combination report containing both ‘os’ and ’non-os’ vulnerability records.

The system has been designed to incorporate 3rd party feeds for other vulnerabilites.


To generate a report of OS package (RPM/DEB/APK) vulnerabilities found in the image including CVE identifier, Vulnerable Package, Severity Level, Vulnerability details and version of fixed package (if available).

# anchorectl image vulnerabilities debian:latest -t os

Currently the following the system draws vulnerability data specifically matched to the following OS distros:

  • Alpine
  • CentOS
  • Debian
  • Oracle Linux
  • Red Hat Enterprise Linux
  • Red Hat Universal Base Image (UBI)
  • Ubuntu
  • Suse Linux
  • Amazon Linux 2
  • Google Distroless

To generate a report of language package (NPM/GEM/Java/Python) vulnerabilities, the system draws vulnerability data from the NVD data feed, and vulnerability reports can be viewed using the ’non-os’ vulnerability type:

# anchorectl image vulnerabilities node:latest -t non-os

To generate a list of all vulnerabilities that can be found, regardless of whether they are against an OS or non-OS package type, the ‘all’ vulnerability type can be used:

# anchorectl image vulnerabilities node:latest -t all

Finally, for any of the above queries, these commands (and other anchorectl commands) can be passed the -o json flag to output the data in JSON format:

# anchorectl -o json image vulnerabilities node:latest -t all

Other options can be reviewed by issuing anchorectl image vulnerabilities --help at any time.

Next Steps

  • Evaluate the image against policies you create.
  • Subscribe to receive notifications when the image is updated, when the policy status changes or when new vulnerabilities are detected.
