CVE-2025-61798 Overview
CVE-2025-61798 is an out-of-bounds read vulnerability affecting Adobe Dimension versions 4.1.4 and earlier. The flaw occurs when the application parses a crafted file, causing a read past the end of an allocated memory structure. An attacker can leverage this issue to execute code in the context of the current user. Exploitation requires user interaction, as a victim must open a malicious file delivered through phishing, web download, or other social engineering channels.
Critical Impact
Successful exploitation allows arbitrary code execution in the context of the logged-in user, compromising confidentiality, integrity, and availability on affected Windows and macOS workstations.
Affected Products
- Adobe Dimension versions 4.1.4 and earlier
- Microsoft Windows installations of Adobe Dimension
- Apple macOS installations of Adobe Dimension

Technical Details for CVE-2025-61798
Vulnerability Analysis
The vulnerability is classified as an out-of-bounds read [CWE-125] in the file parsing logic of Adobe Dimension. When the application processes a maliciously crafted file, it reads memory beyond the boundary of an allocated buffer. This read past the end of an allocated structure can leak adjacent memory contents and, under specific conditions, disrupt control flow in a way that enables arbitrary code execution.
The issue affects desktop installations on both Windows and macOS. Because Dimension is commonly used by design and creative teams, attackers can target these users with project files that appear legitimate.
Root Cause
The root cause is improper validation of input data sizes or offsets during parsing of a Dimension-supported file format. The parser trusts attacker-controlled length, index, or offset fields and dereferences memory outside the allocated buffer. The resulting out-of-bounds read can expose sensitive process memory and feed into a broader exploitation chain that achieves code execution.
Attack Vector
The attack vector is local and requires user interaction. An attacker crafts a malicious file and delivers it to the victim through email attachments, file sharing services, or compromised websites. Opening the file in a vulnerable version of Adobe Dimension triggers the out-of-bounds read. Code executes with the privileges of the user running Dimension, which on most workstations is a standard interactive user account.
The vulnerability mechanism is described in the Adobe Security Advisory APSB25-103. No public proof-of-concept code is available at the time of publication.
Detection Methods for CVE-2025-61798
Indicators of Compromise
- Unexpected child processes spawned by Dimension.exe on Windows or the Adobe Dimension process on macOS, particularly shell, scripting, or LOLBin binaries.
- Adobe Dimension crashes or abnormal terminations correlated with opening files from untrusted sources.
- Outbound network connections initiated by the Dimension process to unfamiliar domains or IP addresses shortly after a file is opened.
Detection Strategies
- Monitor process lineage for Adobe Dimension spawning interpreters such as powershell.exe, cmd.exe, wscript.exe, bash, or osascript.
- Alert on Dimension reading or writing files in unusual locations such as user startup folders, Temp directories, or LaunchAgents.
- Track file format telemetry for Dimension project files arriving via email gateways or external file shares.
Monitoring Recommendations
- Enable endpoint behavioral monitoring focused on memory corruption patterns and exploit-like primitives during file parsing.
- Forward Dimension process and file telemetry to a centralized log platform for correlation with email and web proxy data.
- Review application crash reports for repeated faults in Dimension modules that could indicate exploitation attempts.
How to Mitigate CVE-2025-61798
Immediate Actions Required
- Inventory all Windows and macOS endpoints running Adobe Dimension and identify versions at or below 4.1.4.
- Apply the patched version referenced in the Adobe Security Advisory APSB25-103 as soon as it is available in your environment.
- Instruct users to avoid opening Dimension project files from untrusted or unverified sources until patching is complete.
Patch Information
Adobe has released a security update for Dimension that resolves CVE-2025-61798. Refer to the Adobe Security Advisory APSB25-103 for the fixed version and download links. Customers on managed deployments should distribute the update through their standard software management tooling.
Workarounds
- Restrict file associations so that Adobe Dimension does not automatically open project files received from email or browser downloads.
- Apply email gateway rules to quarantine or flag Dimension-specific file types from external senders.
- Run Dimension under standard user accounts only, never with administrative privileges, to limit the impact of successful exploitation.
# Configuration example: list installed Dimension version on Windows
reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" /s /f "Adobe Dimension"
# On macOS, check the installed Dimension version
mdls -name kMDItemVersion "/Applications/Adobe Dimension/Adobe Dimension.app"
