CVE-2026-48272: Adobe Creative Cloud Desktop RCE Flaw

CVE-2026-48272 Overview

CVE-2026-48272 affects the Adobe Creative Cloud Desktop Application on Microsoft Windows. The flaw is an Uncontrolled Search Path Element weakness [CWE-427] that can lead to arbitrary code execution in the context of the current user. Exploitation requires local access and does not require user interaction, but success depends on conditions outside the attacker's direct control. The scope is changed, meaning a successful exploit can affect resources beyond the vulnerable component's security authority. Adobe published the fix in security bulletin APSB26-77.

Critical Impact
A local attacker who plants a malicious library in a directory that appears earlier in the application's search path can execute arbitrary code with the privileges of the user running Creative Cloud Desktop.

Affected Products

Adobe Creative Cloud Desktop Application (see APSB26-77 for exact fixed versions)
Microsoft Windows hosts running the affected application
Endpoints where the Creative Cloud Desktop service or helper processes execute

Technical Details for CVE-2026-48272

Vulnerability Analysis

The Creative Cloud Desktop Application loads external libraries or executable components using a search path that is not fully controlled by the application. When the operating system resolves a referenced module, it walks a sequence of directories in a defined order. If any writable directory precedes the trusted location, an attacker with local access can drop a malicious file that is loaded in place of the legitimate binary.

Once loaded, the attacker-controlled code runs inside the trusted Creative Cloud process. Because the scope is changed, code executed under the application's context can reach resources outside the immediate process boundary, including data owned by other components the user can access.

Root Cause

The root cause is classified under [CWE-427] Uncontrolled Search Path Element. The application does not fully qualify the path to loadable components or does not validate that the directories in its search order are protected from untrusted writes. As a result, module resolution can pick up an attacker-supplied file before the intended one.

Attack Vector

Exploitation requires local access to the Windows host and low-privileged authenticated access. The attacker plants a crafted library or executable in a directory that the Creative Cloud Desktop process searches before the legitimate location. When the application starts, updates, or triggers a load of the affected component, the malicious module executes with the current user's rights. No user interaction with the malicious file is needed, but attack complexity is high because the attacker must align environmental conditions such as writable path precedence and load timing.

No public proof-of-concept exploit code is available at the time of publication, and the vulnerability is not listed on the CISA Known Exploited Vulnerabilities catalog. Refer to the Adobe Security Update APSB26-77 for vendor-specific technical details.

Detection Methods for CVE-2026-48272

Indicators of Compromise

Unsigned or unexpected DLL and executable files present in directories writable by standard users that fall within the Creative Cloud Desktop search path.
Creative Cloud Desktop processes loading modules from user-writable locations such as %APPDATA%, %TEMP%, or the current working directory rather than Program Files.
New child processes spawned by Creative Cloud helper binaries that perform network, credential, or file-system activity inconsistent with normal application behavior.

Detection Strategies

Hunt for module load events (Sysmon Event ID 7) where the ImageLoaded path is outside the trusted Adobe installation directory but the parent process is a Creative Cloud binary.
Alert on file-creation events that place .dll, .exe, or manifest files matching Adobe module names into user-writable directories in the process search order.
Correlate process-creation telemetry to identify Creative Cloud processes launching interpreters (cmd.exe, powershell.exe) or LOLBins shortly after startup.

Monitoring Recommendations

Enable module and image-load logging on endpoints running Creative Cloud Desktop and forward the events to a central analytics platform.
Baseline the legitimate set of DLLs loaded by Creative Cloud processes so deviations trigger investigation.
Track software inventory to confirm all endpoints receive the fixed version described in APSB26-77.

How to Mitigate CVE-2026-48272

Immediate Actions Required

Apply the Adobe Creative Cloud Desktop updates specified in Adobe Security Update APSB26-77 on all Windows endpoints.
Restrict write permissions on directories that appear in the application's DLL search path so standard users cannot plant modules.
Audit endpoints for pre-existing suspicious files in candidate hijack locations before rolling out the patch.

Patch Information

Adobe addressed CVE-2026-48272 in the fixed release documented in bulletin APSB26-77. Administrators should refer to the vendor advisory for the exact fixed version numbers and deployment guidance. Updates can be delivered through the Creative Cloud Desktop auto-updater or enterprise deployment tooling.

Workarounds

Enforce least-privilege configuration so standard users cannot write to directories in the Creative Cloud search order.
Apply Windows AppLocker or Windows Defender Application Control policies that restrict execution of unsigned binaries from user-writable locations.
Where possible, remove PATH entries that reference user-writable directories from systems that run Creative Cloud Desktop.

bash

# Configuration example: tighten ACLs on a directory frequently abused for search-order hijacking
icacls "C:\ProgramData\Adobe" /inheritance:r
icacls "C:\ProgramData\Adobe" /grant:r "Administrators:(OI)(CI)F" "SYSTEM:(OI)(CI)F" "Users:(OI)(CI)RX"
