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 · uneditedIllustrator is affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.

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 confidenceAdobe Illustrator contains an improper input validation vulnerability that allows arbitrary code execution when a user opens a maliciously crafted file. The vulnerability results in code running in the context of the current user, potentially allowing privilege escalation or session compromise. Scope is changed, indicating the vulnerability impacts components beyond the vulnerable software itself.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Adobe Illustrator is installedCheck for Adobe Illustrator application in system application folders (Windows: Program Files/Adobe, macOS: /Applications) or query installed programs via system utilityAffected if Adobe Illustrator is present on the system
-
Determine installed Adobe Illustrator versionAccess version information: Windows - via Help > About Adobe Illustrator or right-click exe > Properties > Details; macOS - right-click app > Get Info or run 'mdls' commandAffected if Version cannot be determined or is outside documented version ranges
-
Compare version against affected rangesMatch the installed version number to the vulnerable ranges: 29.0 through 29.8.8.x, or 30.0 through 30.5.xAffected if Installed version is 29.0 to 29.8.8.x OR 30.0 to 30.5.x (any build within these ranges)
-
Assess user interaction exposureEvaluate likelihood of opening untrusted or maliciously crafted .AI, .EPS, or other Illustrator file formats from unknown sourcesAffected if Users routinely open files from untrusted or external sources without validation
User is affected if Adobe Illustrator version falls within 29.0 to 29.8.8.x or 30.0 to 30.5.x AND the system handles untrusted Illustrator files

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data29.8.930.6
Apply Adobe's official security patches for Illustrator once released. Until patches are available, instruct users to avoid opening files from untrusted sources and consider deploying additional file-opening restrictions or sandboxing for the application.
