CVE-2026-48382: Adobe Experience Manager Privilege Escalation

CVE-2026-48382 Overview

CVE-2026-48382 is an Incorrect Authorization vulnerability [CWE-863] in Adobe Experience Manager (AEM). The flaw allows attackers to execute arbitrary code in the context of the current user. Successful exploitation can grant elevated access or control over the victim's account or session.

The vulnerability is network-exploitable, requires no authentication, and demands no user interaction. The scope is changed, meaning exploitation impacts resources beyond the vulnerable component. Adobe disclosed the issue in Security Bulletin APSB26-152.

Critical Impact
Unauthenticated attackers can achieve arbitrary code execution against Adobe Experience Manager instances reachable over the network, with no user interaction required.

Affected Products

Adobe Experience Manager (see Adobe Security Bulletin APSB26-152 for specific affected versions)

Technical Details for CVE-2026-48382

Vulnerability Analysis

The vulnerability stems from an Incorrect Authorization weakness in Adobe Experience Manager. The application performs an authorization check but fails to enforce it correctly for certain requests. Attackers can reach protected functionality without holding the privileges the application should require.

Because the issue results in arbitrary code execution, an attacker who reaches the vulnerable code path can run attacker-controlled logic within the user context processing the request. The changed scope indicates that compromise of the AEM component affects additional security authorities, such as backend services, content repositories, or integrated applications.

AEM commonly serves public-facing marketing sites and internal content workflows. A successful attack can lead to content tampering, exfiltration of unpublished assets, pivoting into integrated identity or storage systems, and persistence through modified components or scheduled jobs.

Root Cause

The root cause is improper authorization logic [CWE-863]. The application grants access to a resource or operation without correctly validating that the actor holds the required permissions. Combined with code execution surfaces inside AEM, authorization bypass translates directly into arbitrary code execution.

Attack Vector

An attacker sends crafted network requests to an exposed AEM instance. No credentials and no user interaction are required. The attacker reaches a privileged function through the broken authorization check and triggers code execution in the current user's context.

No verified public exploit code is available at the time of writing. Technical details are described in prose only; see the Adobe Security Bulletin APSB26-152 for vendor guidance.

Detection Methods for CVE-2026-48382

Indicators of Compromise

Unexpected HTTP requests to AEM administrative, Sling, or JCR endpoints from untrusted sources.
Creation or modification of AEM nodes, components, or scheduled jobs outside normal change windows.
New or unexpected processes spawned by the AEM Java process, including shells or scripting interpreters.
Outbound network connections from AEM hosts to previously unseen external addresses.

Detection Strategies

Alert on anonymous or low-privilege sessions that successfully reach administrative or authoring endpoints.
Correlate authorization decisions in AEM logs with the resulting HTTP response codes to find bypass patterns.
Monitor for Java process behavior indicative of command execution, such as java.exe or java spawning cmd.exe, powershell.exe, /bin/sh, or bash.

Monitoring Recommendations

Centralize AEM access logs, error logs, and request logs into a SIEM for correlation with endpoint telemetry.
Baseline normal author and publish traffic patterns and alert on deviations in request volume or source geography.
Enable file integrity monitoring on AEM installation directories and content repository stores.

How to Mitigate CVE-2026-48382

Immediate Actions Required

Apply the updates listed in Adobe Security Bulletin APSB26-152 as a priority.
Inventory all AEM Author, Publish, and Dispatcher instances, including non-production environments, and confirm patch status.
Restrict network exposure of AEM Author instances to trusted administrative networks and VPN only.
Rotate credentials, API keys, and service account tokens accessible from AEM hosts after patching.

Patch Information

Adobe published fixes in Security Bulletin APSB26-152. Review the bulletin for specific affected versions and the corresponding fixed releases, and apply the vendor-supplied updates to all AEM instances. See Adobe Security Bulletin APSB26-152 for the full remediation matrix.

Workarounds

Place AEM behind a web application firewall and block unauthenticated requests to administrative, Sling, and JCR endpoints.
Enforce Dispatcher filter rules that deny access to internal paths and selectors not required for public delivery.
Remove or disable unused AEM components, bundles, and sample content to reduce exploitable surface.
