CVE-2025-30314
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 · uneditedAdobe Connect versions 12.8 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.
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 confidenceAdobe Connect versions 12.8 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability in certain form fields that do not properly sanitize user input. An authenticated attacker can inject malicious JavaScript payloads into these fields, which persist in the application. When other users view pages containing these compromised fields, the embedded scripts execute in their browsers, potentially allowing session hijacking or credential theft.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Adobe Connect versionAccess the Adobe Connect login page or admin interface and locate the version number typically displayed in the footer or about section. Alternatively, check the installation directory for version files or query the system if centrally managed.Affected if Installed version is 12.8 or earlier (any version < 12.9)
-
Confirm application is accessibleVerify that Adobe Connect is running and reachable via its web interface. Check network exposure and whether the login page loads.Affected if The application is deployed and accessible to users or attackers
-
Verify authentication is enabledConfirm that user authentication is configured and functional. The vulnerability requires an authenticated attacker to inject the XSS payload.Affected if User authentication is enabled and accounts can be created or accessed
-
Identify form input pointsReview common Adobe Connect form fields where user input is captured, such as meeting room names, user profile fields, or event registration forms. These are potential injection points for the stored XSS.Affected if User-editable form fields exist in the application that accept text input and display back to users
You are affected if Adobe Connect version is earlier than 12.9 and the application accepts user input in form fields that are displayed to other users.
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.
dbcve · scoped12.9
Implement proper input validation and output encoding on the vulnerable form fields to neutralize script injection attempts. Apply vendor-provided patches by upgrading to a version beyond 12.8 once released.
Adobe Connect 12.9
- Upgrade Adobe Connect to version 12.9 or later to resolve the stored XSS vulnerability
- After upgrading, verify that the Adobe Connect application is functioning correctly
- Confirm the vulnerability is remediated by testing that user inputs in form fields are properly sanitized
