CVE-2025-54233 Overview
CVE-2025-54233 is an out-of-bounds read vulnerability in Adobe Framemaker versions 2020.8, 2022.6, and earlier. The flaw enables disclosure of sensitive memory when a user opens a maliciously crafted file. Adobe published the vulnerability in its APSB25-83 security bulletin.
The issue is classified under [CWE-125] (Out-of-Bounds Read) and requires user interaction for exploitation. The attack vector is local, meaning an attacker must convince a victim to open a malicious document. Successful exploitation exposes process memory but does not directly impact integrity or availability.
Critical Impact
Attackers can read sensitive memory contents from the Framemaker process, potentially exposing data useful for chaining with other exploits.
Affected Products
- Adobe Framemaker 2020.8 and earlier 2020.x releases
- Adobe Framemaker 2022.6 and earlier 2022.x releases
- Microsoft Windows platforms running affected Framemaker versions

Technical Details for CVE-2025-54233
Vulnerability Analysis
Adobe Framemaker contains an out-of-bounds read defect in its file parsing logic. When the application processes a crafted document, it reads memory beyond the intended buffer boundary. This behavior leaks adjacent heap or stack contents into structures accessible to the parser.
The disclosed memory may contain pointers, session data, or fragments of other opened documents. Attackers commonly use out-of-bounds reads to bypass Address Space Layout Randomization (ASLR) as a precursor to code execution exploits. The vulnerability alone does not grant code execution, but the leaked data increases the reliability of follow-on attacks.
Root Cause
The root cause is missing bounds validation during document parsing. Framemaker consumes attacker-controlled length or offset values from the input file without verifying that they fall within allocated buffer boundaries. This allows the parser to dereference memory outside the intended region.
Adobe has not published detailed technical breakdowns of the parsing routines involved. Refer to the Adobe Security Advisory APSB25-83 for additional context.
Attack Vector
Exploitation requires an attacker to deliver a malicious Framemaker document to a target user. Common delivery methods include phishing email attachments, watering hole downloads, and shared file repositories. The victim must open the file with a vulnerable Framemaker version for the vulnerability to trigger.
No verified proof-of-concept code is publicly available for this vulnerability. Description in prose only per available data.
Detection Methods for CVE-2025-54233
Indicators of Compromise
- Unexpected Framemaker process crashes when opening documents from untrusted sources
- Framemaker documents (.fm, .book, .mif) arriving from external senders with unusual structural properties
- Framemaker processes spawning unexpected child processes after opening a document
Detection Strategies
- Monitor endpoint telemetry for FrameMaker.exe crash events correlated with recently opened files
- Deploy YARA or content inspection rules on email gateways to flag malformed Framemaker file structures
- Correlate document open events with subsequent anomalous memory access patterns in EDR telemetry
Monitoring Recommendations
- Track Framemaker version inventory across endpoints to identify unpatched hosts
- Log and review file provenance for documents opened in Framemaker, prioritizing files from external sources
- Alert on Framemaker process behavior deviations, including unusual memory reads or handle activity
How to Mitigate CVE-2025-54233
Immediate Actions Required
- Update Adobe Framemaker to the versions specified in Adobe Security Advisory APSB25-83
- Restrict opening Framemaker documents received from untrusted or external sources until patching is complete
- Communicate the risk to authoring teams that regularly handle Framemaker files
Patch Information
Adobe released fixed versions of Framemaker in security bulletin APSB25-83. Administrators should upgrade all Framemaker 2020.x installations beyond 2020.8 and all Framemaker 2022.x installations beyond 2022.6 to receive the fix. Consult the Adobe Security Advisory APSB25-83 for exact version numbers and download instructions.
Workarounds
- Enforce application allowlisting to prevent execution of unpatched Framemaker binaries
- Open untrusted Framemaker documents inside isolated virtual machines or sandboxed environments
- Apply email attachment filtering rules that quarantine Framemaker file types from external senders
