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 28.6, 27.9.5 and earlier are affected by an Integer Overflow or Wraparound vulnerability that could result in arbitrary code execution in the context of the current user. 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 · high confidence

Adobe Illustrator versions 28.6 and earlier contain an integer overflow vulnerability in file parsing logic. When a user opens a specially crafted malicious file, the integer overflow can be triggered, leading to heap corruption and arbitrary code execution in the context of the current user.

MitigationUpdate Adobe Illustrator to the latest patched version released by Adobe, and enforce user awareness training to avoid opening files from untrusted sources.

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. Verify Adobe Illustrator is installed
    Check for Adobe Illustrator in the system applications or installed programs list. On Windows, review Add/Remove Programs or the installation directory. On macOS, check /Applications for Adobe Illustrator.app.
    Affected if Adobe Illustrator is present on the system
  2. Determine the installed version number
    Open Adobe Illustrator and navigate to Help > About Adobe Illustrator, or check the version through the application launcher. On Windows, the version may also be visible in the executable properties or installer records.
    Affected if A version number is displayed that can be compared to the affected ranges
  3. Compare installed version against affected ranges
    Check if the installed version falls within: 27.0.0 through 27.9.6 (inclusive of 27.0.0, exclusive of 27.9.6), OR 28.0 through 28.7.0 (inclusive of 28.0, exclusive of 28.7.1). Versions 27.9.6 and up, or 28.7.1 and up, are not affected.
    Affected if The installed version is 27.0.0 to 27.9.5, or 28.0 to 28.7.0
  4. Identify exposure to the attack vector
    Determine if the user opens AI, EPS, or other file formats processed by Illustrator from external or untrusted sources. The vulnerability is triggered during file parsing when a specially crafted malicious file is opened.
    Affected if Users open Illustrator files from untrusted or unknown sources without verification

The system is affected if Adobe Illustrator version 27.0.0-27.9.5 or 28.0-28.7.0 is installed and users may open files from untrusted sources.

Upgrade available Upgrade to 27.9.6 / 28.7.1 or later
Fixed in 27.9.628.7.1
Interim mitigation

Update Adobe Illustrator to the latest patched version released by Adobe, and enforce user awareness training to avoid opening files from untrusted sources.

Recommended fix High confidence

Adobe Illustrator 27.9.6 or later for the 27.x branch; Adobe Illustrator 28.7.1 or later for the 28.x branch

  1. 1. Determine the currently installed Adobe Illustrator version by opening Illustrator and navigating to Help > About Adobe Illustrator
  2. 2. If using version 27.0.0 through 27.9.5, upgrade to version 27.9.6 or later
  3. 3. If using version 28.0 through 28.6, upgrade to version 28.7.1 or later
  4. 4. Download the update from the official Adobe website or use the Adobe Creative Cloud desktop application to install the update
  5. 5. Verify the update was successful by checking the version number again after installation
  6. 6. As a general security practice, avoid opening untrusted or unexpected files received from untrusted sources
Caveat Adobe minor version updates typically do not introduce breaking changes; however, always review release notes for any notable changes before production deployment
