Adobe Experience Manager Missing Authentication Security Feature Bypass
CVE-2026-48252 is a missing authentication for critical function vulnerability in Adobe Experience Manager (AEM). Insufficient authentication enforcement on a security-sensitive function permits a remote attacker to bypass security measures and perform unauthorized write operations. The issue affects AEM as a Cloud Service through release 2026.5.0, AEM 6.5 LTS through Service Pack 1, and AEM 6.5 through version 6.5.24. It is rated CVSS 8.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N).
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation allows an unauthenticated remote attacker to bypass security controls and gain unauthorized write access. Integrity is highly affected, and the changed scope indicates that the vulnerable component can affect a different security authority than the component that contains the flaw. No confidentiality or availability impact is identified.
If you can’t patch tonight, do this now.
Apply the vendor security updates promptly. Until remediation is complete, restrict network access to AEM authoring, administrative, and write-capable interfaces to trusted users and networks; minimize external exposure; enforce least privilege; and monitor for anomalous or unauthorized write requests.
Patch, then assume compromise.
Upgrade AEM as a Cloud Service to release 2026.6.0 or later. For AEM 6.5 LTS, apply Service Pack 2 and the vendor hotfix for this issue. For AEM 6.5, upgrade to Service Pack 25 and apply the corresponding vendor hotfix. Follow Adobe's AEM security update guidance for deployment-specific installation procedures.
