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
HCL AION is affected by a Cookie with Insecure, Improper, or Missing SameSite vulnerability. This can allow cookies to be sent in cross-site requests, potentially increasing exposure to cross-site request forgery and related security risks. This issue affects AION: 2.0.

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

HCL AION 2.0 sets cookies without a proper SameSite attribute, allowing browsers to send these cookies in cross-site requests. This exposes the application to Cross-Site Request Forgery (CSRF) attacks where malicious sites can trigger authenticated actions on behalf of users.

MitigationConfigure all cookies to include the SameSite attribute set to 'Strict' or 'Lax' mode in the application code or server configuration to prevent cookies from being sent in cross-site requests.

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. Verify HCL AION version
    Check the installed version of HCL AION in your environment (typically via application metadata, about page, or installation directory) and compare it to version 2.0.0
    Affected if The installed version is exactly 2.0.0
  2. Inspect cookie headers in HTTP responses
    Use browser developer tools (Network tab) or a proxy tool to capture HTTP responses from the HCL AION application. Examine Set-Cookie headers for the SameSite attribute
    Affected if Any Set-Cookie header is missing the SameSite attribute (or the attribute is absent entirely)
  3. Review application cookie configuration
    Check application configuration files or source code that handles cookie creation to see if SameSite is explicitly set on cookies
    Affected if Cookies are being set without a SameSite attribute defined in the configuration or code

You are affected if you are running HCL AION version 2.0.0 and the application sets cookies without the SameSite attribute in their headers or configuration.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

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

Configure all cookies to include the SameSite attribute set to 'Strict' or 'Lax' mode in the application code or server configuration to prevent cookies from being sent in cross-site requests.
