Executive brief
Adobe Experience Manager, a platform used by organizations to manage digital content and assets, is affected by a security flaw that allows unauthorized users to bypass authentication. An attacker could exploit this to gain unauthorized write access to the system, potentially altering website content or configuration without a valid login. This could lead to unauthorized data modification and damage to an organization's digital presence and reputation.
Technical details
Adobe Experience Manager is vulnerable to a Missing Authentication for Critical Function (CWE-306) flaw. The vulnerability exists because certain critical functions do not properly enforce authentication requirements, allowing a remote, unauthenticated attacker to bypass security measures. Successful exploitation grants the attacker unauthorized write access to the system. The attack can be carried out over the network without any user interaction, and the vulnerability carries a changed scope (S:C) impact. Adobe has released updates and hotfixes to address this issue across Cloud Service and 6.5 versions.
Affected products
- Adobe Experience Manager as a Cloud Service <= 2026.5.0
- Adobe Experience Manager 6.5 LTS <= SP1
- Adobe Experience Manager 6.5 <= 6.5.24
