CVE-2025-47132 Overview
CVE-2025-47132 is an out-of-bounds write vulnerability [CWE-787] 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 crafted file. Adobe published a fix in security advisory APSB25-66.
Exploitation requires user interaction, which lowers the likelihood of mass exploitation but still presents risk in targeted phishing scenarios. The vulnerability affects Adobe Framemaker installations running on Microsoft Windows.
Critical Impact
Successful exploitation grants arbitrary code execution at the privilege level of the user opening the malicious Framemaker document.
Affected Products
- Adobe Framemaker 2020.8 and earlier
- Adobe Framemaker 2022.6 and earlier
- Microsoft Windows (host platform)

Technical Details for CVE-2025-47132
Vulnerability Analysis
The vulnerability is an out-of-bounds write [CWE-787] in Adobe Framemaker's file parsing logic. When Framemaker processes a malformed document, it writes data past the bounds of an allocated buffer. The corrupted memory region can include adjacent heap structures, function pointers, or control data used by the application.
An attacker who controls the contents of the malicious file can shape this out-of-bounds write to redirect execution flow. Because Framemaker runs in the security context of the invoking user, any code executed by the attacker inherits that user's privileges and access to local resources.
The published EPSS metric indicates a low predicted probability of exploitation activity in the near term, consistent with the local attack vector and required user interaction. However, document-based exploits remain a common initial access technique in targeted attacks.
Root Cause
The root cause is insufficient bounds checking during the parsing of attacker-controlled file structures within Framemaker. The application writes parsed values into a fixed-size buffer without validating that the input length stays within the allocated region.
Attack Vector
The attack vector is local and requires user interaction. An attacker delivers a crafted Framemaker document through phishing email, a malicious download, or a shared file location. The victim must open the file in a vulnerable Framemaker version to trigger the out-of-bounds write and subsequent code execution.
No public proof-of-concept exploit, ExploitDB entry, or CISA KEV listing is associated with this CVE at the time of writing. Consult the Adobe Security Advisory APSB25-66 for vendor technical details.
Detection Methods for CVE-2025-47132
Indicators of Compromise
- Unexpected child processes spawned by FrameMaker.exe, particularly command interpreters such as cmd.exe, powershell.exe, or wscript.exe.
- Framemaker process crashes or repeated Windows Error Reporting events referencing access violations during document open operations.
- Inbound .fm, .book, .mif, or other Framemaker-associated files arriving from external email senders or untrusted shares.
Detection Strategies
- Monitor process lineage for Framemaker spawning interpreters, scripting hosts, or LOLBins, which is uncommon during normal authoring workflows.
- Alert on Framemaker writing or modifying executable files, scheduled tasks, or run-key registry entries.
- Inspect endpoint telemetry for memory access violation crashes within FrameMaker.exe correlated with recent document opens.
Monitoring Recommendations
- Capture and retain process creation, file write, and module load events from hosts running Adobe Framemaker.
- Track inventory and version data for Framemaker installations to confirm exposure to the affected 2020.8 and 2022.6 baselines.
- Forward email gateway telemetry for Framemaker-associated attachments and correlate with endpoint document-open events.
How to Mitigate CVE-2025-47132
Immediate Actions Required
- Inventory all Windows endpoints running Adobe Framemaker and identify systems running 2020.8, 2022.6, or earlier releases.
- Apply the updates referenced in Adobe Security Advisory APSB25-66 on every affected host.
- Restrict opening of Framemaker files originating from external or untrusted sources until patching completes.
Patch Information
Adobe released fixed builds for Framemaker in advisory APSB25-66. Administrators should download the updated installers from Adobe and deploy them through standard software distribution tooling. Verify version numbers post-deployment to confirm remediation.
Workarounds
- Block delivery of Framemaker-associated file types at the email gateway when business workflows allow.
- Apply least-privilege controls so users running Framemaker do not hold local administrator rights.
- Enable Windows attack surface reduction rules that restrict Office and document-handling applications from spawning child processes where supported by policy.
# Configuration example: query installed Framemaker version on Windows endpoints
reg query "HKLM\SOFTWARE\Adobe\FrameMaker" /s /v Version
