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 · high confidence

Adobe Connect versions 12.6, 11.4.7 and earlier contain a reflected XSS vulnerability where unsanitized user input is echoed back in HTTP responses, allowing execution of arbitrary JavaScript in victim browsers when they visit attacker-crafted URLs.

MitigationUpgrade Adobe Connect to the latest patched version; apply input validation and output encoding to all user-supplied parameters as a defense-in-depth measure.

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 Adobe Connect is installed
    Check for Adobe Connect by looking in common installation directories (e.g., C:\Program Files\Adobe\Adobe Connect on Windows, /opt/adobe-connect on Linux) or by identifying the application responding on default ports 80, 443, or 8443
    Affected if Adobe Connect is found and running in the environment
  2. Determine the installed version
    Locate version information in the installation directory, typically in a version file, or access the Adobe Connect admin dashboard and look for the version display, or query the application directly for version information
    Affected if The installed version cannot be determined or is found
  3. Compare against affected version ranges
    Review the discovered version number and compare it against the vulnerable ranges: version < 11.4.9 OR version >= 12.0 AND version < 12.7
    Affected if The installed version falls within < 11.4.9 or >= 12.0 but < 12.7
  4. Assess reflected XSS exposure
    Since this is a reflected XSS where unsanitized user input is echoed back in HTTP responses, test suspected input parameters in URLs by injecting test payloads and observing whether the input is returned unencoded in the response
    Affected if User-supplied parameters are reflected in responses without proper sanitization or encoding

A user is affected if Adobe Connect is installed and the version falls below 11.4.9 or is between 12.0 and 12.6 inclusive, and the application echoes URL parameters back in responses without encoding.

Upgrade available Upgrade to 11.4.9 / 12.7 or later
Fixed in 11.4.912.7
Interim mitigation

Upgrade Adobe Connect to the latest patched version; apply input validation and output encoding to all user-supplied parameters as a defense-in-depth measure.

Recommended fix High confidence

Upgrade to Adobe Connect 11.4.9 or later for the 11.x branch; upgrade to 12.7 or later for the 12.x branch

  1. Identify your current Adobe Connect version in the admin dashboard or system information
  2. Review Adobe Connect 11.4.9 and 12.7 release notes for new features, deprecated functionality, and any breaking changes
  3. Ensure your environment meets the system requirements for the target version
  4. Create a complete backup of the Adobe Connect database, configuration files, and custom content
  5. Test the upgrade in a staging or development environment before applying to production
  6. Schedule a maintenance window as upgrades may require downtime
  7. Download the appropriate installer from Adobe's official download center or licensed distribution channel
  8. Run the installer and follow the on-screen upgrade instructions
Caveat Review Adobe release notes for version-specific changes - some custom templates, SCORM packages, or integrations may require updates after major version upgrades
