Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Illustrator versions 29.8.4, 30.1 and earlier are affected by an Out-of-bounds Read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to access sensitive information stored in memory. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

An out-of-bounds read vulnerability in Adobe Illustrator versions 29.8.4, 30.1 and earlier allows attackers to read memory beyond allocated boundaries when a victim opens a malicious file, potentially exposing sensitive information stored in memory.

MitigationUsers should avoid opening untrusted or unsolicited files and update to a patched version when Adobe releases an update. Organizations may consider file type restrictions or application sandboxing as additional safeguards.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Adobe Illustrator version
    Windows: Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Illustrator\InstallPath or check Help > About Illustrator. macOS: Right-click Adobe Illustrator in Applications and select Get Info, or open Illustrator and go to Help > About Illustrator.
    Affected if Version is 29.0 through 29.8.4, or 30.0 through 30.1 (any version >= 29.0 and < 29.8.5, or >= 30.0 and < 30.2).
  2. Confirm version falls within affected ranges
    Compare your installed version number against the affected ranges: versions 29.0 to 29.8.4 (before 29.8.5) and versions 30.0 to 30.1 (before 30.2).
    Affected if Installed version matches any version in these ranges.
  3. Verify file parsing is active (default state)
    This vulnerability triggers when Illustrator opens files - no special feature needs to be enabled. By default, Illustrator can open .ai, PDF, and other supported file formats.
    Affected if Illustrator is installed and capable of opening files, which is the default configuration.

You are affected if Adobe Illustrator is installed with any version from 29.0 to 29.8.4, or 30.0 to 30.1.

Recommended fix High confidence

Adobe Illustrator 29.8.5 (for 29.x branch) or 30.2 (for 30.x branch)

  1. Check current Adobe Illustrator version: In Illustrator, go to Help > About Adobe Illustrator
  2. Close all Adobe applications before updating
  3. Open Adobe Creative Cloud desktop app or navigate to Adobe's official download center at helpx.adobe.com
  4. Look for Adobe Illustrator updates or patches
  5. Download and install the appropriate update: If currently on version 29.x, install 29.8.5 or later; If currently on version 30.x, install 30.2 or later
  6. Restart Adobe Illustrator after the update completes
