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 2025.3, 12.10 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an 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. Scope is changed.

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 2025.3, 12.10 and earlier contain a reflected Cross-Site Scripting (XSS) vulnerability. An attacker can craft a malicious URL containing JavaScript payload that gets reflected back and executed in victim's browser when they visit the link. The CVSS scope change indicates the vulnerability can impact resources beyond the vulnerable component.

MitigationApply vendor-provided patches/updates to Adobe Connect to the latest version. Until patched, implement URL parameter validation and output encoding on affected endpoints, and educate users about not clicking untrusted links.

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 Adobe Connect version
    Log into the Adobe Connect administration console and navigate to the About section, or check the version displayed on the login page. Alternatively, check the version from the installer file or installed program listing.
    Affected if The installed version is 12.10 or earlier, or any version below 12.11.
  2. Identify Adobe Connect Desktop Application version
    Open the Adobe Connect Desktop Application, go to Help > About Adobe Connect, or check the version from the installed programs list in the operating system.
    Affected if The installed version is 2025.3 or earlier, or any version below 2025.9.15.
  3. Check if Adobe Connect web interface is exposed
    Verify whether the Adobe Connect web interface is accessible from user browsers, either internally or externally. Attempt to access the login page or common endpoints via HTTP/HTTPS.
    Affected if The web interface is accessible and users can be tricked into clicking malicious URLs.
  4. Review URL parameters for input validation
    Inspect common Adobe Connect URL parameters (such as meeting IDs, user inputs in forms, or query strings) to determine if user-supplied data is being reflected in responses without proper encoding. Manually test by injecting a benign test string like <script>alert(1)</script> in URL parameters to see if it is reflected unescaped.
    Affected if User input in URL parameters is reflected in the response without HTML encoding, indicating lack of output encoding.

A user is affected if their Adobe Connect installation is version 12.10 or earlier, or their Desktop Application is 2025.3 or earlier, and the web interface is accessible to users who could be targeted with malicious URLs.

Interim mitigation

Apply vendor-provided patches/updates to Adobe Connect to the latest version. Until patched, implement URL parameter validation and output encoding on affected endpoints, and educate users about not clicking untrusted links.

Recommended fix Moderate confidence

Adobe Connect version 12.11 or later; Adobe Connect Desktop Application version 2025.9.15 or later

  1. 1. Identify the Adobe Connect deployment in your environment (Connect server and/or Connect Desktop Application)
