CVE-2026-106625 Overview
CVE-2026-106625 is an out-of-bounds write vulnerability [CWE-787] in Adobe FrameMaker. Attackers can exploit this flaw to execute arbitrary code in the context of the current user. Exploitation requires user interaction, specifically opening a malicious file crafted by the attacker.
The vulnerability carries a CVSS 3.1 base score of 7.8 and is tracked under Adobe security bulletin APSB26-172. It is a local attack vector issue with low complexity and no privilege requirements. No public proof-of-concept exploit or active exploitation has been reported at the time of publication.
Critical Impact
Successful exploitation allows arbitrary code execution with the privileges of the user running Adobe FrameMaker, enabling full compromise of the user's session and data.
Affected Products
- Adobe FrameMaker (versions identified in Adobe advisory APSB26-172)
- Windows installations of Adobe FrameMaker
- Documentation workflows that process untrusted .fm or related FrameMaker document files

Technical Details for CVE-2026-106625
Vulnerability Analysis
The flaw is an out-of-bounds write condition within Adobe FrameMaker's file parsing logic. When FrameMaker processes a specially crafted document, it writes data past the bounds of an allocated memory buffer. This corrupts adjacent memory structures and can be leveraged to redirect execution flow.
An attacker crafts a malicious FrameMaker file and delivers it to a target through email, a shared document location, or a compromised website. The user must open the file for exploitation to succeed. Once triggered, the attacker executes arbitrary code at the same privilege level as the FrameMaker process.
Root Cause
The underlying issue is classified as [CWE-787] Out-of-bounds Write. The parser does not correctly validate size or offset values embedded in the document before writing data into memory. This absence of boundary checking allows attacker-controlled input to overwrite memory that lies outside the intended buffer.
Attack Vector
The attack vector is local and requires user interaction. The attacker cannot trigger the vulnerability remotely without social engineering. Delivery typically relies on phishing or supply-chain scenarios where a user is persuaded to open the malicious document. Successful exploitation yields code execution with the current user's privileges, which may be used as a foothold for lateral movement or privilege escalation through chained vulnerabilities.
Adobe does not disclose detailed technical specifics for this issue. Refer to the Adobe Security Patch APSB26-172 advisory for authoritative vendor information.

Stop Exploit AttemptsDetection Methods for CVE-2026-106625
Indicators of Compromise
- Unexpected child processes spawned by FrameMaker.exe, such as cmd.exe, powershell.exe, or scripting hosts
- FrameMaker process crashes or abnormal terminations correlated with opening external documents
- Inbound FrameMaker files (.fm, .mif, .book) delivered from untrusted email senders or external file shares
- Outbound network connections from FrameMaker.exe to unknown or low-reputation hosts
Detection Strategies
- Monitor process-creation telemetry for FrameMaker spawning interpreters, shells, or living-off-the-land binaries
- Track file writes performed by FrameMaker to startup, scheduled task, or user profile locations
- Inspect email gateway logs for FrameMaker file attachments and quarantine for sandbox analysis
- Correlate Windows Error Reporting events referencing FrameMaker modules with user file-open activity
Monitoring Recommendations
- Enable detailed process and command-line auditing on endpoints that run Adobe FrameMaker
- Forward endpoint, email gateway, and proxy telemetry to a centralized analytics platform for correlation
- Alert on FrameMaker modules loading unsigned DLLs or executing from user-writable paths
How to Mitigate CVE-2026-106625
Immediate Actions Required
- Apply the Adobe FrameMaker security update referenced in bulletin APSB26-172 on all affected systems
- Instruct users to avoid opening FrameMaker files received from untrusted or unverified sources
- Restrict FrameMaker installations to users with a documented business need
- Enforce least-privilege user accounts to limit the impact of successful exploitation
Patch Information
Adobe has published fixes in the security bulletin Adobe Security Patch APSB26-172. Review the advisory to identify affected FrameMaker versions and the corresponding fixed releases, then schedule remediation according to exposure.
Workarounds
- Block inbound .fm, .mif, and .book file types at the email gateway until patches are deployed
- Open untrusted FrameMaker documents only inside an isolated virtual machine or sandbox
- Apply application-control policies that prevent FrameMaker from launching child processes such as shells and scripting hosts
- Disable or uninstall FrameMaker on systems where it is not actively required
# Example application-control rule concept (pseudocode)
Deny Process: FrameMaker.exe -> Child: cmd.exe, powershell.exe, wscript.exe, cscript.exe
Allow Process: FrameMaker.exe -> File Read: C:\Users\*\Documents\*.fm (trusted paths only)
