CVE-2025-49529: Adobe Illustrator RCE Vulnerability

CVE-2025-49529 Overview

CVE-2025-49529 is an Access of Uninitialized Pointer vulnerability [CWE-824] affecting Adobe Illustrator versions 28.7.6, 29.5.1, and earlier. Adobe published the advisory on July 8, 2025. The flaw allows arbitrary code execution in the context of the current user when a victim opens a malicious file. Exploitation requires user interaction, limiting mass exploitation but enabling targeted attacks through social engineering. The vulnerability affects Illustrator installations on both Apple macOS and Microsoft Windows platforms.

Critical Impact
Successful exploitation enables arbitrary code execution under the privileges of the logged-in user, potentially leading to full system compromise when the user holds administrative rights.

Affected Products

Adobe Illustrator 28.7.6 and earlier (2024 release line)
Adobe Illustrator 29.5.1 and earlier (2025 release line)
Affected on both Apple macOS and Microsoft Windows

Technical Details for CVE-2025-49529

Vulnerability Analysis

The vulnerability is classified under [CWE-824] Access of Uninitialized Pointer. Adobe Illustrator dereferences a pointer that was never initialized to a valid memory address. When the application parses a crafted file, the code path reaches the uninitialized pointer and uses it for read, write, or function call operations. This produces undefined behavior that an attacker can shape into arbitrary code execution.

Root Cause

The root cause is missing initialization of a pointer variable inside Illustrator's file parsing logic. When a malformed object or structure is encountered, the parser fails to assign a valid value to the pointer before use. The contents of the uninitialized memory location can be influenced by prior allocations or by data embedded in the malicious file, giving an attacker control over the dereferenced address.

Attack Vector

Exploitation requires local user interaction. An attacker delivers a malicious Illustrator file through email, web download, or shared storage. The victim opens the file in a vulnerable version of Illustrator. The parser reaches the uninitialized pointer, and the attacker-controlled memory contents redirect execution flow to attacker-supplied code. The resulting process executes with the privileges of the current user.

No public proof-of-concept exploit is available for CVE-2025-49529 at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2025-49529

Indicators of Compromise

Unexpected child processes spawned by Illustrator.exe on Windows or the Adobe Illustrator process on macOS, particularly command interpreters such as cmd.exe, powershell.exe, or /bin/sh
Illustrator process crashes or access violation events logged shortly after opening .ai, .eps, .pdf, or .svg files from untrusted sources
Outbound network connections originating from the Illustrator process to unknown external hosts
Newly created executables or scripts in user-writable directories following the opening of a design file

Detection Strategies

Monitor process lineage where Illustrator is the parent process and flag deviations from normal child process behavior
Inspect file open telemetry for Illustrator handling files originating from email attachments, browser downloads, or removable media
Hunt for memory access violation events and exception codes consistent with pointer dereference faults in the Illustrator process
Correlate Illustrator crash events with subsequent persistence mechanisms such as scheduled task creation or registry Run key modification

Monitoring Recommendations

Enable endpoint detection telemetry covering process creation, file writes, and network connections from Adobe Creative Cloud applications
Forward Illustrator application crash logs and Windows Error Reporting events to a centralized log platform for analysis
Track Illustrator version inventory across endpoints to identify hosts still running vulnerable builds
Alert on Illustrator opening files from temporary directories, download folders, or mounted external volumes

How to Mitigate CVE-2025-49529

Immediate Actions Required

Upgrade Adobe Illustrator to the fixed versions identified in Adobe advisory APSB25-65 across all Windows and macOS endpoints
Inventory all systems running Illustrator 28.7.6, 29.5.1, or earlier and prioritize patching of users who routinely handle external design files
Instruct users to avoid opening Illustrator files received from unverified sources until patches are applied
Review endpoint protection policies to ensure script and process behavior monitoring is active for Adobe applications

Patch Information

Adobe released patched versions of Illustrator on July 8, 2025, as part of security bulletin APSB25-65. Customers should update through the Adobe Creative Cloud desktop application or by downloading the fixed installers directly from Adobe. Refer to the Adobe Illustrator Security Advisory for the exact patched version numbers and download instructions.

Workarounds

Restrict Illustrator file handling to files originating from trusted internal sources until patching completes
Apply application control policies to block execution of child processes spawned by Illustrator that fall outside an approved allowlist
Use email gateway rules to quarantine Illustrator file types from external senders pending review
Run Illustrator under standard user accounts rather than administrative accounts to limit the impact of successful exploitation
