CVE-2020-9730: Out-of-bounds memory access could lead to code execution

A memory corruption vulnerability exists in InDesign 15.1.1 (and earlier versions). Insecure handling of a malicious indd file could be abused to cause an out-of-bounds memory access, potentially resulting in code execution in the context of the current user.

Security readout for executives and security teams

Plain-English summary

CVE-2020-9730 is a high-severity Adobe InDesign flaw. A user opening a malicious INDD file could trigger memory corruption and potentially let attacker-controlled code run with that user's privileges.

Executive priority

Treat this as a workstation compromise risk for design and marketing users. It is not known exploited from the supplied evidence, but successful exploitation could run code as the user.

Technical view

The issue is an out-of-bounds memory access in Adobe InDesign 15.1.1 and earlier, categorized as CWE-788. CVSS 3.1 is 7.8 with local attack vector, low complexity, no privileges required, and required user interaction.

Likely exposure

Exposure is most likely on workstations with Adobe InDesign 15.1.1 or earlier, especially users who receive INDD files from external parties.

Exploitation context

The provided sources do not show active exploitation or KEV listing. Exploitation requires convincing a user to open a malicious INDD file, so phishing or shared design-file workflows are the plausible entry points.

Researcher notes

Evidence is limited to the CVE record and Adobe advisory reference. No CPEs are listed in the bundle. Validate affected builds directly against Adobe APSB20-52 before making scope decisions.

Mitigation direction

  • Check Adobe APSB20-52 for the fixed InDesign release and update accordingly.
  • Prioritize systems that handle external INDD files or shared design assets.
  • Restrict opening untrusted INDD files until affected installations are remediated.
  • Use least-privilege desktop accounts where InDesign is required.

Validation and detection

  • Inventory installed Adobe InDesign versions across managed endpoints.
  • Flag InDesign 15.1.1 and earlier as affected.
  • Confirm remediation status against Adobe APSB20-52 guidance.
  • Review workflows that accept INDD files from external sources.
