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
1Password SCIM Bridge before 1.6.2 mishandles validation of authenticated requests for log files, leading to disclosure of a TLS private key.

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 · high confidence

The 1Password SCIM Bridge before version 1.6.2 contains a vulnerability where validation of authenticated requests for log files is improperly handled. This flaw allows an authenticated attacker to access log files that should be restricted, and through this access pattern, obtain a TLS private key used by the SCIM Bridge.

MitigationUpgrade 1Password SCIM Bridge to version 1.6.2 or later to remediate this vulnerability. After upgrading, rotate the exposed TLS private key and any credentials that may have been compromised.

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 if 1Password SCIM Bridge is deployed
    Search your container registry, Kubernetes cluster, or infrastructure for resources related to 1Password SCIM Bridge such as containers, pods, deployments, or services named 'scim' or '1password-scim'. Check your Docker, Kubernetes, or orchestration configuration files for scim-bridge references.
    Affected if 1Password SCIM Bridge is present in your environment
  2. Determine the installed version
    Check the version of your deployed SCIM Bridge. For container deployments, inspect the container image tag (e.g., 'docker images' or container registry tags). For Helm deployments, check 'helm list' and the chart version. For Kubernetes, inspect the deployment YAML for the image tag including version.
    Affected if The version cannot be determined or is within the range 1.0.0 to less than 1.6.2
  3. Compare version against affected range
    If a version number was obtained, verify it falls within the affected range: 1.0.0 <= version < 1.6.2. Any version from 1.0.0 through 1.6.1 is vulnerable.
    Affected if The installed version is 1.0.0, 1.1.x, 1.2.x, 1.3.x, 1.4.x, 1.5.x, or 1.6.0 or 1.6.1
  4. Check for log file access anomalies
    Review access logs, audit logs, or web server logs for the SCIM Bridge for unusual GET requests to log file paths. Look for requests to paths like /logs, /var/log, or similar endpoints that may indicate log file enumeration.
    Affected if Unusual or unauthorized access patterns to log files are found in the SCIM Bridge logs

Your environment is affected if 1Password SCIM Bridge is deployed and the installed version is 1.0.0 or higher but lower than 1.6.2.
