Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Insecure permissions in fabedge v0.8.1 allows attackers to access sensitive data and escalate privileges by obtaining the service account's token.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

In fabedge v0.8.1, insecure file or directory permissions allow unauthorized local users to access service account tokens. Attackers who gain local access can read these tokens and use them to authenticate to the Kubernetes API, accessing sensitive data and escalating privileges within the cluster.

MitigationRestrict file and directory permissions to ensure service account tokens are only accessible to the intended processes (e.g., chmod 600 on token files, proper ownership). Apply least-privilege RBAC policies and audit all sensitive file access patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Fabedge installation and version
    Run 'fabctl version' or check the Fabedge deployment manifests for the version field. If using Kubernetes, check the Fabedge podspec for the image tag version.
    Affected if The installed version is Fabedge v0.8.1 or the specific version cannot be determined but Fabedge is present.
  2. Locate service account token files
    Search for token files in Fabedge's data and runtime directories. Common paths include /var/run/secrets/kubernetes.io/serviceaccount/, /opt/fabedge/, or custom paths configured in Fabedge's configuration files.
    Affected if Service account token files exist in Fabedge's accessible directories.
  3. Check file permissions on token files
    Run 'ls -la' on identified token files and check the permission bits. Look for files with permissions like 644, 664, or any world-readable/group-readable setting.
    Affected if Token files have permissions that allow read access to non-owner users (e.g., permissions include 'r--r--r--', 'rw-r--r--', or similar).
  4. Check directory permissions on token-containing directories
    Run 'ls -ld' on directories containing the token files. Verify the directory permissions are not world-readable or group-readable.
    Affected if Directories containing tokens have overly permissive access (e.g., 'drwxr-xr-x' or similar that allows unauthorized users to traverse or list).
  5. Test unauthorized user access
    If possible, switch to a non-privileged local user account and attempt to read the token files using 'cat' or 'read' commands on the identified paths.
    Affected if A non-owner, non-admin user can successfully read the service account token files.

A user is affected if Fabedge v0.8.1 is installed AND service account token files or their directories have permissions that allow access by unauthorized local users.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict file and directory permissions to ensure service account tokens are only accessible to the intended processes (e.g., chmod 600 on token files, proper ownership). Apply least-privilege RBAC policies and audit all sensitive file access patterns.
