Security readout for executives and security teams
Plain-English summary
CVE-2022-30666 is an Adobe Illustrator memory disclosure issue. A malicious Illustrator file could cause the application to read memory it should not, potentially exposing sensitive memory and helping bypass defenses such as ASLR. It requires a user to open a malicious file.
Executive priority
Treat this as a moderate-priority desktop application patching issue. It is not evidenced as actively exploited, but affected creative teams may have realistic exposure because opening external design files is part of normal business workflow.
Technical view
The vulnerability is an out-of-bounds read in Adobe Illustrator, tracked as CWE-125. The CVSS 3.1 score is 5.5 with local attack vector, low complexity, no privileges required, required user interaction, high confidentiality impact, and no integrity or availability impact.
Likely exposure
Exposure is most likely on endpoints running Adobe Illustrator 26.0.2 and earlier or 25.4.5 and earlier, especially where staff open Illustrator files from external clients, suppliers, or public sources.
Exploitation context
The provided sources do not establish active exploitation, and the CVE is not marked KEV. Exploitation requires convincing a victim to open a malicious file, so phishing, client file exchange, or compromised shared assets are the relevant contexts.
Researcher notes
Evidence supports memory disclosure and ASLR mitigation bypass potential, but not code execution or active exploitation. The source bundle does not provide detailed root cause, proof-of-concept status, or explicit fixed version data beyond the Adobe advisory reference.
Mitigation direction
- Check Adobe APSB22-26 for the vendor-approved fixed Illustrator versions.
- Update affected Illustrator installations according to Adobe guidance.
- Reduce handling of untrusted Illustrator files on vulnerable endpoints.
- Use endpoint controls to quarantine suspicious design-file attachments.
- Prioritize design, marketing, and production teams that exchange external files.
Validation and detection
- Inventory installed Adobe Illustrator versions across managed endpoints.
- Identify systems running 26.0.2 or earlier, or 25.4.5 or earlier.
- Confirm remediation status against Adobe APSB22-26 guidance.
- Review mail and file-sharing workflows for external Illustrator files.
- Document any unsupported or unmanaged Illustrator installations.
