CVE-2025-49526: Adobe Illustrator RCE Vulnerability

CVE-2025-49526 Overview

CVE-2025-49526 is an out-of-bounds write vulnerability [CWE-787] affecting Adobe Illustrator versions 28.7.6, 29.5.1, and earlier. The flaw allows arbitrary code execution in the context of the current user when a victim opens a crafted malicious file. Adobe disclosed the issue in security bulletin APSB25-65 covering Windows and macOS installations of Illustrator.

Exploitation requires user interaction, limiting mass attack scenarios but enabling targeted campaigns against design teams, marketing departments, and creative agencies that routinely process untrusted vector graphics files.

Critical Impact

Successful exploitation grants attackers the ability to execute arbitrary code with the privileges of the logged-in user, potentially leading to full workstation compromise.

Affected Products

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

Discovery Timeline

• 2025-07-08 - CVE-2025-49526 published to the National Vulnerability Database
• 2025-07-10 - Last updated in NVD database

Technical Details for CVE-2025-49526

Vulnerability Analysis

The vulnerability is classified as an out-of-bounds write [CWE-787] in Adobe Illustrator's file parsing logic. When Illustrator processes a maliciously crafted file, the application writes data beyond the boundaries of an allocated memory buffer. This memory corruption can overwrite adjacent heap structures, function pointers, or return addresses used by the application.

Attackers who control the contents written out of bounds can redirect execution flow to attacker-supplied shellcode. The result is arbitrary code execution under the security context of the user running Illustrator. On workstations where designers operate with local administrator rights, compromise extends to the entire host.

Root Cause

The root cause is insufficient bounds checking during the parsing of a structured file format consumed by Illustrator. Adobe's advisory APSB25-65 does not enumerate the specific file format or parser routine. Out-of-bounds write defects in graphics applications typically stem from trusting length fields embedded in file headers without validating them against allocated buffer sizes.

Attack Vector

The attack vector is local and requires user interaction. An attacker delivers a malicious Illustrator-compatible file through email attachments, file-sharing platforms, compromised websites, or supply chain channels such as stock asset marketplaces. When the victim opens the file in a vulnerable Illustrator build, the parser triggers the out-of-bounds write and executes the embedded payload.

The vulnerability does not require elevated privileges to exploit, and no authentication to Illustrator or the host is needed beyond a logged-in user session.

No verified public proof-of-concept code is available for CVE-2025-49526. Refer to the Adobe Security Advisory APSB25-65 for vendor-supplied technical context.

Detection Methods for CVE-2025-49526

Indicators of Compromise

• Unexpected child processes spawned by Illustrator.exe on Windows or the Adobe Illustrator process on macOS, particularly shell interpreters such as cmd.exe, powershell.exe, or /bin/sh
• Illustrator process crashes followed by anomalous outbound network connections to unrecognized external hosts
• Newly written executable files, scripts, or scheduled tasks in user-writable directories shortly after opening a vector graphics file

Detection Strategies

• Monitor endpoint telemetry for process lineage anomalies where Illustrator parents non-graphics processes, a strong signal of exploitation of file-parser flaws
• Hunt for Illustrator binaries loading unusual DLLs or dylibs from temporary or user profile paths
• Alert on memory access violations and faulting modules within the Illustrator process space using crash telemetry

Monitoring Recommendations

• Inventory installed Illustrator versions across all endpoints and flag hosts running 28.7.6, 29.5.1, or earlier
• Track inbound .ai, .eps, .pdf, and .svg files from email and external file shares for behavioral analysis in a sandbox
• Correlate file-open events with subsequent process creation and network activity to surface exploitation chains

How to Mitigate CVE-2025-49526

Immediate Actions Required

• Upgrade Adobe Illustrator to the fixed versions identified in Adobe Security Advisory APSB25-65 on all Windows and macOS endpoints
• Block or quarantine Illustrator-compatible files originating from untrusted external sources at the email gateway
• Instruct users to avoid opening unsolicited .ai, .eps, or related vector files until patches are deployed

Patch Information

Adobe released fixed versions of Illustrator as documented in Adobe Security Advisory APSB25-65. Administrators should deploy the updates through the Adobe Creative Cloud desktop application or enterprise deployment tooling such as the Adobe Admin Console.

Workarounds

• Restrict Illustrator users to standard, non-administrative accounts to limit the blast radius of code execution
• Open suspicious vector files only inside an isolated virtual machine or sandboxed environment disconnected from production data
• Enable operating-system exploit mitigations such as Windows Exploit Protection and macOS Hardened Runtime for the Illustrator process
