CVE-2025-43567
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 reflected 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. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high.
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 reflected XSS vulnerability where malicious scripts can be injected into form fields. When victims browse to pages with the compromised field, the attacker's JavaScript executes in their browser, enabling session hijacking and potential privilege escalation.

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.
-
Identify Adobe Connect versionAccess the Adobe Connect admin dashboard or check the installation directory for version information. On Windows, this is often found in the installation folder or via the admin interface at /admin/Affected if The installed version is 12.8 or earlier (versions prior to 12.9)
-
Confirm web interface is accessibleVerify that the Adobe Connect web interface is reachable and form-based input fields are exposed to usersAffected if The web interface is accessible and accepts user input in form fields without sanitization
-
Review form field handlingInspect the application's response when submitting data through form input fields, particularly looking for reflected parameters in the responseAffected if User-supplied input in form fields is reflected back in the HTML response without proper encoding
-
Check for XSS indicators in logsReview Adobe Connect server logs and HTTP traffic for suspicious script payloads in form parameter valuesAffected if Logs contain unexpected script tags or JavaScript code in form submission parameters
You are affected if Adobe Connect version 12.8 or earlier is installed and the web interface with form fields is accessible to 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
Apply the vendor-supplied security patch for Adobe Connect 12.8 or later; as an interim control, deploy WAF rules to filter malicious script payloads in affected form field parameters.
12.9 or later
- Upgrade Adobe Connect to version 12.9 or later
- After upgrading, verify the XSS vulnerability is remediated by testing the previously vulnerable form fields
- Consult Adobe Connect 12.9 release notes for any additional configuration requirements
