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
Adobe Connect versions 12.6, 11.4.7 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an unauthenticated attacker is able to convince a victim to visit a URL referencing a vulnerable page, malicious JavaScript content may be executed within the context of the victim's browser.

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

Adobe Connect versions 12.6, 11.4.7 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. An unauthenticated attacker can craft a malicious URL containing JavaScript payload that gets reflected back and executed within the victim's browser when they visit the link.

MitigationApply input validation and output encoding to the vulnerable parameter(s) on the affected page(s). Implement Content-Security-Policy headers as an additional defense layer.

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 Adobe Connect is installed
    Locate the Adobe Connect installation directory or check for the Connect service running on the host. Common paths include C:\Connect\ or /opt/connect/ on Linux systems.
    Affected if Adobe Connect server software is present on the system
  2. Identify the installed Adobe Connect version
    Access the Adobe Connect login page and look for version information in the footer, or check the admin dashboard under System Information. Alternatively, check the installer or version file in the installation directory.
    Affected if The version number cannot be determined or is not visible
  3. Compare your version against affected ranges
    Check if the installed version is less than 11.4.9, or greater than or equal to 12.0 but less than 12.7
    Affected if Installed version falls within < 11.4.9 or >= 12.0 and < 12.7
  4. Verify web interface accessibility
    Confirm the Adobe Connect web interface (typically ports 80/443 or 8080/8443) is accessible from the network
    Affected if The web interface is exposed and the version is affected

If Adobe Connect is installed and the version is below 11.4.9, or between 12.0 and 12.6 inclusive, the environment is vulnerable to reflected XSS via malicious URL parameters.

Recommended fix Moderate confidence

Adobe Connect 12.7 or 11.4.9 (depending on your current major version branch)

  1. 1. Backup the current Adobe Connect installation and database before upgrading.
  2. 2. Download Adobe Connect version 12.7 (or 11.4.9 for the 11.x branch) from the official Adobe website or license portal.
  3. 3. Stop the Adobe Connect services on the server.
  4. 4. Install the updated version following Adobe's standard upgrade procedures.
  5. 5. Verify the installation by logging into the Adobe Connect management console.
  6. 6. Test critical functionality to ensure the upgrade did not disrupt existing workflows.
  7. 7. Confirm the version number reflects the patched release (12.7 or 11.4.9).
