CVE-2025-54256

Code execution via undisclosed cross-site request forgery

Published Sep 9, 2025 · Updated Sep 9, 2025

Cross-site request forgery in Adobe Dreamweaver Desktop 21.5 and earlier allows attackers to execute code as the current user. Adobe identifies the flaw as CSRF but has not published the affected request handler or the operation it performs without validating request origin. A victim must click a malicious link; successful exploitation runs arbitrary code with that user's privileges on Windows or macOS.
