CVE-2025-54284 Overview
CVE-2025-54284 is an out-of-bounds write vulnerability [CWE-787] affecting Adobe Illustrator versions 29.7, 28.7.9, and earlier on Windows and macOS. Successful exploitation allows arbitrary code execution in the context of the current user. The flaw requires user interaction: a victim must open a crafted file in Illustrator. Adobe addressed the issue in security bulletin APSB25-102.
Critical Impact
Opening a malicious Illustrator file enables arbitrary code execution under the privileges of the logged-in user.
Affected Products
- Adobe Illustrator 29.7 and earlier (2025 release)
- Adobe Illustrator 28.7.9 and earlier (2024 release)
- Apple macOS and Microsoft Windows installations of Illustrator

Technical Details for CVE-2025-54284
Vulnerability Analysis
The vulnerability is an out-of-bounds write in Adobe Illustrator's file parsing logic. When Illustrator processes a malformed document, the application writes data past the bounds of an allocated buffer. An attacker controls the contents and length of that write, which corrupts adjacent memory structures. Crafted memory corruption can be steered into control-flow hijacking, yielding arbitrary code execution in the user's session.
The issue carries an EPSS probability of 0.031%, indicating low observed exploitation activity at this time. No public proof-of-concept exploit has been published, and the CVE is not listed in the CISA Known Exploited Vulnerabilities catalog.
Root Cause
The root cause is insufficient validation of size or index values during parsing of an attacker-supplied file. Illustrator computes a destination offset or buffer length from data inside the file without bounding it against the allocated region. Because the parser trusts the embedded structure, the write proceeds past the buffer boundary and corrupts heap or stack memory.
Attack Vector
Exploitation requires local user interaction. An attacker delivers a malicious Illustrator file through email, a shared drive, a web download, or a collaboration platform. When the user opens the file in a vulnerable Illustrator build, the parser triggers the out-of-bounds write. Code then executes with the privileges of the current user, enabling credential theft, persistence, or lateral movement.
No verified exploit code is publicly available. Refer to Adobe Security Advisory APSB25-102 for vendor technical context.
Detection Methods for CVE-2025-54284
Indicators of Compromise
- Unexpected child processes spawned by Illustrator.exe on Windows or the Adobe Illustrator process on macOS, such as cmd.exe, powershell.exe, bash, or osascript.
- Illustrator process crashes or Watson/CrashReporter entries shortly after a user opens an .ai, .eps, .pdf, or .svg file from an untrusted source.
- Outbound network connections originating from the Illustrator process to unfamiliar domains or IP addresses.
- New files written into user-writable autostart locations following the opening of a design file.
Detection Strategies
- Hunt for Illustrator parent processes spawning script interpreters or shells, which indicates post-exploitation execution.
- Inspect endpoint telemetry for memory allocation faults, access violations, or exceptions inside the Illustrator process.
- Correlate email and web gateway logs that delivered Illustrator-compatible attachments with subsequent endpoint activity from the recipient host.
Monitoring Recommendations
- Enable command-line and process-tree logging on workstations that run Adobe Creative Cloud applications.
- Forward Illustrator crash and reliability events to the central log platform for retroactive hunting.
- Track Adobe Creative Cloud version inventory and alert when hosts remain on Illustrator builds at or below 29.7 or 28.7.9.
How to Mitigate CVE-2025-54284
Immediate Actions Required
- Update Adobe Illustrator to the fixed versions documented in APSB25-102 on every Windows and macOS endpoint.
- Block inbound delivery of Illustrator file formats from untrusted external senders at the email gateway until patching is verified.
- Instruct designers and content teams not to open Illustrator files received from unverified sources.
Patch Information
Adobe released fixed builds of Illustrator 2025 and Illustrator 2024 in security bulletin APSB25-102. Deploy the update through Adobe Creative Cloud Desktop or the enterprise Admin Console. Confirm successful installation by checking the Illustrator About dialog for a version above 29.7 or 28.7.9 respectively.
Workarounds
- Restrict file associations so Illustrator does not automatically open files retrieved from email or browser downloads.
- Run Illustrator under a standard user account, never as administrator, to limit the impact of successful exploitation.
- Quarantine inbound .ai, .eps, and related design files in a sandbox or detonation service before delivery to end users.
