CVE-2025-49533Public exploitNetwork attack vector

Pre-auth code execution via serDoc deserialization

Published Jul 8, 2025 · Updated Feb 26, 2026

Deserialization in Adobe Experience Manager Managed Services 6.5.23.0 and earlier allows remote attackers to execute arbitrary code. The unauthenticated GetDocumentServlet decodes the serDoc request parameter, then passes its bytes to ObjectInputStream.readObject without a class allowlist. A network-reachable AEM Forms on JEE deployment is enough; a crafted gadget chain runs commands in the application-server process.
