CVE-2025-54232 Overview
CVE-2025-54232 is a Use After Free vulnerability affecting Adobe Framemaker versions 2020.8, 2022.6, and earlier. The flaw can result in arbitrary code execution in the context of the current user. Exploitation requires user interaction: a victim must open a malicious file crafted by an attacker.
Adobe published this issue in security bulletin APSB25-83. The vulnerability is tracked under CWE-416 (Use After Free) and affects Framemaker installations on Microsoft Windows.
Critical Impact
An attacker who convinces a user to open a malicious Framemaker document can execute arbitrary code with the privileges of that user, enabling local compromise of the workstation.
Affected Products
- Adobe Framemaker 2020.8 and earlier 2020.x releases
- Adobe Framemaker 2022.6 and earlier 2022.x releases
- Microsoft Windows hosts running affected Framemaker versions

Technical Details for CVE-2025-54232
Vulnerability Analysis
The vulnerability is a Use After Free condition [CWE-416] within Adobe Framemaker's file parsing logic. Framemaker frees an object during document processing and subsequently references the dangling pointer. When an attacker controls the freed memory region, the stale reference enables manipulation of program flow.
Successful exploitation yields arbitrary code execution with the privileges of the user running Framemaker. Confidentiality, integrity, and availability are each fully impacted on the local host. The attack requires local access and user interaction, which limits remote mass exploitation but suits targeted phishing scenarios delivering malicious documents.
Root Cause
The defect arises from improper object lifetime management during parsing of attacker-controlled file structures. Framemaker dereferences a pointer after the underlying allocation has been released. Reusing memory between the free and the subsequent access allows the attacker to substitute crafted data, including function pointers or vtable entries, leading to control of the instruction pointer.
Attack Vector
An attacker delivers a malicious Framemaker document through email, web download, or shared storage. When the victim opens the file in a vulnerable version of Framemaker, the parser triggers the use-after-free condition. The attacker's payload then executes in the user's security context. No network access to the target is required, and no privileges are needed prior to exploitation beyond persuading the user to open the file.
No verified public proof-of-concept exists at the time of writing. Refer to the Adobe Security Advisory APSB25-83 for vendor-supplied technical context.
Detection Methods for CVE-2025-54232
Indicators of Compromise
- Unexpected FrameMaker.exe child processes such as cmd.exe, powershell.exe, or rundll32.exe
- Framemaker process crashes followed by suspicious file writes to user-writable directories
- Inbound .fm, .book, or .mif files arriving via email or download from untrusted sources
- Outbound network connections originating from FrameMaker.exe to previously unseen destinations
Detection Strategies
- Monitor process lineage for Framemaker spawning interpreters, scripting hosts, or LOLBins
- Alert on memory access violations and exception events generated by FrameMaker.exe
- Inspect email gateways and web proxies for Framemaker document attachments from external senders
- Apply YARA rules to flag malformed Framemaker file structures referenced in vendor or community research
Monitoring Recommendations
- Forward endpoint process, file, and network telemetry to a centralized analytics platform for correlation
- Track Framemaker version inventory across endpoints to identify unpatched installations
- Review user-mode crash dumps from Windows Error Reporting for repeated Framemaker faults indicating exploitation attempts
How to Mitigate CVE-2025-54232
Immediate Actions Required
- Update Adobe Framemaker to the fixed releases identified in Adobe Security Advisory APSB25-83
- Block delivery of Framemaker file types from untrusted external sources at email and web gateways
- Instruct users to avoid opening Framemaker documents received from unverified senders
- Run Framemaker under standard user accounts to limit blast radius if code execution occurs
Patch Information
Adobe addressed CVE-2025-54232 in updates published alongside bulletin APSB25-83 on August 12, 2025. Administrators should deploy the vendor-supplied installers to upgrade Framemaker 2020.x past version 2020.8 and Framemaker 2022.x past version 2022.6. Consult the advisory for the exact fixed build numbers and download locations.
Workarounds
- Restrict Framemaker file associations so documents do not open automatically from browsers or mail clients
- Enable Windows Defender Exploit Guard and Attack Surface Reduction rules to constrain Office and document-handler child processes
- Apply application allowlisting to prevent unauthorized binaries spawned by FrameMaker.exe from executing
- Isolate documentation authoring workstations on segmented networks until patches are deployed
# Example: query installed Framemaker version on Windows endpoints
reg query "HKLM\SOFTWARE\Adobe\FrameMaker" /s /v Version
