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
Incorrect authentication vulnerability in OpenSIAC, which could allow an attacker to impersonate a person using Cl@ve as an authentication method.

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

OpenSIAC contains an incorrect authentication vulnerability in its Cl@ve integration that allows an attacker to impersonate legitimate users. The authentication mechanism fails to properly validate Cl@ve authentication tokens or session data, enabling unauthorized access to the system through impersonation.

MitigationUpdate OpenSIAC to a version that corrects the Cl@ve authentication validation logic, ensuring proper verification of authentication tokens and session integrity.

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. Confirm OpenSIAC installation
    Locate the OpenSIAC installation directory or check running services for OpenSIAC components
    Affected if OpenSIAC is not present in the environment
  2. Identify installed OpenSIAC version
    Access the application's version information through its web interface, check version files in the installation directory, or run version command if available
    Affected if Cannot determine version - comparison with corrected releases needed when available
  3. Verify Cl@ve authentication is enabled
    Inspect authentication configuration files, settings panel, or module list to determine if the Cl@ve integration module is active
    Affected if Cl@ve integration is disabled - the vulnerability only applies when Cl@ve authentication is in use
  4. Examine Cl@ve token validation settings
    Review authentication configuration files related to Cl@ve for token validation parameters, session handling settings, and any custom authentication logic
    Affected if Non-standard or missing token validation configuration is observed for Cl@ve integration

Environment is affected if running a vulnerable OpenSIAC version with Cl@ve authentication enabled and improper token/session validation present in configuration
