CVE-2025-47122 Overview
CVE-2025-47122 is a heap-based buffer overflow vulnerability affecting Adobe Framemaker versions 2020.8, 2022.6 and earlier. The flaw allows arbitrary code execution in the context of the current user when a victim opens a malicious file. Adobe published the security advisory APSB25-66 to address the issue.
The vulnerability is categorized under [CWE-122] Heap-based Buffer Overflow. Exploitation requires user interaction, which limits remote weaponization but remains effective in phishing and supply chain scenarios targeting technical documentation teams.
Critical Impact
Successful exploitation enables arbitrary code execution with the privileges of the logged-in user, allowing attackers to install programs, modify data, or create new accounts.
Affected Products
- Adobe Framemaker 2020.8 and earlier
- Adobe Framemaker 2022.6 and earlier
- Microsoft Windows hosts running affected Framemaker versions

Technical Details for CVE-2025-47122
Vulnerability Analysis
The vulnerability is a heap-based buffer overflow in Adobe Framemaker's file parsing logic. When Framemaker processes a crafted document, the application writes data past the bounds of a heap-allocated buffer. This memory corruption can overwrite adjacent heap metadata or function pointers used by the application.
Attackers control the contents written into adjacent memory regions. By manipulating heap layout and corrupting pointer structures, an attacker achieves arbitrary code execution within the Framemaker process. Code runs at the privilege level of the user who opened the file.
The issue is local in attack vector because the malicious payload must be delivered as a file the user opens. Delivery typically occurs through email attachments, shared drives, or download links targeting documentation engineers and technical writers.
Root Cause
The root cause is improper validation of size or length values during parsing of Framemaker document structures. The vulnerable code path allocates a heap buffer based on one value while copying data based on another, producing an out-of-bounds write [CWE-122]. Adobe has not published the specific component or parser implicated in the bulletin.
Attack Vector
The attack vector is local with required user interaction. An attacker crafts a malicious Framemaker-compatible document and delivers it to a target. When the victim opens the file in a vulnerable Framemaker version, the parser triggers the overflow and executes attacker-controlled code. See the Adobe Security Advisory APSB25-66 for vendor details.
Detection Methods for CVE-2025-47122
Indicators of Compromise
- Unexpected child processes spawned by FrameMaker.exe, such as cmd.exe, powershell.exe, or rundll32.exe
- Framemaker process crashes or access violations logged in Windows Event Viewer near document open events
- Inbound documents with .fm, .mif, .book, or related Framemaker extensions from untrusted senders
- Outbound network connections originating from the Framemaker process to unknown hosts
Detection Strategies
- Monitor process lineage where FrameMaker.exe is the parent of shell or scripting interpreters
- Inspect Windows Error Reporting and crash dumps for heap corruption signatures in Framemaker
- Apply behavioral detection on suspicious memory allocation patterns and code execution from heap regions inside the Framemaker process
Monitoring Recommendations
- Centralize endpoint telemetry for Framemaker process activity, file opens, and child process creation
- Alert on Framemaker spawning network connections or writing executables to disk
- Track Framemaker version inventory across endpoints to identify hosts running 2020.8, 2022.6, or earlier
How to Mitigate CVE-2025-47122
Immediate Actions Required
- Apply the Adobe Framemaker updates referenced in APSB25-66 on all affected endpoints
- Block delivery of Framemaker file types from untrusted external senders at the email gateway
- Restrict Framemaker execution to users with documented business need
Patch Information
Adobe addressed CVE-2025-47122 in the security bulletin APSB25-66. Administrators should upgrade Framemaker 2020 past version 2020.8 and Framemaker 2022 past version 2022.6 using the versions listed in the vendor advisory. Verify patch deployment through software inventory tooling.
Workarounds
- Do not open Framemaker documents from unverified sources until the patch is applied
- Run Framemaker under a standard user account rather than an administrator to limit post-exploitation impact
- Use application allowlisting to prevent Framemaker from launching child processes such as shells and scripting engines
# Example: query installed Framemaker version on Windows endpoints
reg query "HKLM\SOFTWARE\Adobe\FrameMaker" /s /v Version
