CVE-2025-30313: Adobe Illustrator Information Disclosure

CVE-2025-30313 Overview

CVE-2025-30313 is an out-of-bounds read vulnerability [CWE-125] affecting Adobe Illustrator versions 28.7.6, 29.5.1, and earlier on both Windows and macOS. The flaw allows an attacker to read memory outside the intended buffer boundary, potentially disclosing sensitive process memory. Exploitation requires local user interaction. A victim must open a specially crafted file for the vulnerability to trigger. Adobe published a security advisory addressing the issue on the Adobe HelpX portal. The vulnerability carries a CVSS 3.1 base score of 5.5 with confidentiality impact only, and no known public exploit or CISA KEV listing exists at this time.

Critical Impact
Successful exploitation can disclose sensitive process memory to an attacker, potentially exposing data useful for bypassing memory protections such as ASLR.

Affected Products

Adobe Illustrator 28.7.6 and earlier
Adobe Illustrator 29.5.1 and earlier
Microsoft Windows and Apple macOS installations of Illustrator

Technical Details for CVE-2025-30313

Vulnerability Analysis

The vulnerability is an out-of-bounds read classified under [CWE-125]. Illustrator reads memory beyond the boundary of an allocated buffer while parsing attacker-controlled file data. The read operation returns data from adjacent memory regions that were not intended to be accessible in that context. This exposed data can include heap metadata, pointers, or fragments of unrelated documents. Attackers can use disclosed pointers to defeat Address Space Layout Randomization (ASLR) and pair the leak with a separate memory corruption bug for reliable code execution. The bug affects both Windows and macOS builds, indicating the defect resides in shared cross-platform parsing code rather than an OS-specific component.

Root Cause

The root cause is missing or insufficient bounds validation in an Illustrator file parser. When Illustrator processes structured file input, an index or length field is trusted without verification against the actual buffer size. The parser then reads past the allocated region. Adobe has not published detailed internals; refer to the Adobe Illustrator Security Advisory APSB25-65 for vendor-supplied context.

Attack Vector

The attack vector is local and requires user interaction. An attacker crafts a malicious Illustrator-compatible file and delivers it through email, chat, a shared drive, or a web download. The victim must open the file in a vulnerable Illustrator version. No elevated privileges or authentication are required on the target host. The vulnerability does not affect integrity or availability, only confidentiality.

// No verified proof-of-concept code is available for CVE-2025-30313.
// The vulnerability is triggered by parsing a malformed Illustrator file
// where an unchecked length or index field causes the parser to read
// beyond an allocated buffer, disclosing adjacent memory contents.

Detection Methods for CVE-2025-30313

Indicators of Compromise

Unexpected Illustrator process crashes or memory-access exceptions correlated with opening files from untrusted sources.
Illustrator opening .ai, .eps, .pdf, or .svg files delivered from external email attachments or messaging platforms.
Anomalous child processes spawned by Illustrator.exe shortly after a suspicious file open.

Detection Strategies

Inventory endpoints running Illustrator and flag versions at or below 28.7.6 and 29.5.1.
Monitor endpoint telemetry for Illustrator process faults, especially access violations, that follow file-open events.
Inspect email and web gateways for Illustrator file formats originating from untrusted senders.

Monitoring Recommendations

Enable file-open auditing for creative applications and forward events to a central SIEM or data lake.
Correlate Illustrator crashes with the hash and origin of the opened file to identify targeted delivery.
Track patch compliance for Adobe Creative Cloud applications through your endpoint management platform.

How to Mitigate CVE-2025-30313

Immediate Actions Required

Update Adobe Illustrator to the fixed versions listed in Adobe Security Bulletin APSB25-65.
Instruct users to avoid opening Illustrator files received from untrusted or unverified sources until patching is complete.
Verify Creative Cloud auto-update is enabled across managed endpoints.

Patch Information

Adobe released fixed builds addressing CVE-2025-30313 as documented in security bulletin APSB25-65. Deploy the latest Illustrator release through Adobe Creative Cloud or your enterprise software distribution system. Confirm remediation by checking the installed Illustrator version against Adobe's advisory.

Workarounds

Restrict Illustrator file handling to files sourced from trusted internal repositories until patches are applied.
Apply application-level attack surface reduction where feasible to limit child-process creation from Illustrator.
Use email gateway policies to quarantine Illustrator file attachments from external senders during the patch window.
