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
Cross-site scripting vulnerability in Cybozu Garoon 4.0.0 to 4.10.1 allows remote attackers to inject arbitrary web script or HTML via the application 'Mail'.

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

Cross-site scripting vulnerability in Cybozu Garoon versions 4.0.0 to 4.10.1 allows remote attackers to inject arbitrary web script or HTML via the Mail application. The vulnerability stems from insufficient input validation in the Mail module, enabling malicious script execution in the context of affected users' sessions.

MitigationUpgrade Cybozu Garoon to version 4.10.2 or later to obtain the vendor patch. Alternatively, apply available security patches from Cybozu. Until patched, consider disabling or restricting access to the Mail application for untrusted users.

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 Cybozu Garoon is installed
    Identify whether the Cybozu Garoon product is running in your environment by checking for garoon-related processes, services, or web applications
    Affected if Cybozu Garoon is present in the environment
  2. Determine the installed Garoon version
    Locate and read the version information for your Garoon installation (typically accessible via the product's about page, admin interface, or version file)
    Affected if The installed version falls within the range 4.0.0 to 4.10.1 (inclusive)
  3. Confirm the Mail application is enabled
    Check whether the Mail module/application is active and accessible to users in your Garoon configuration
    Affected if The Mail application is enabled and accessible to users (the vulnerability only affects environments where Mail is in use)

Your environment is affected if Cybozu Garoon versions 4.0.0 through 4.10.1 are installed AND the Mail application is enabled and accessible to users.
