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
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.

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

Memory corruption vulnerability in Adobe InDesign 15.1.1 and earlier versions where insecure handling of a maliciously crafted INDD file leads to out-of-bounds memory access, potentially allowing arbitrary code execution in the context of the current user.

MitigationUpdate InDesign to version 15.1.2 or later to patch the vulnerability, and implement user awareness training to prevent opening untrusted INDD files from unknown 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. Check installed InDesign version on Windows
    Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\InDesign\InstallVersion, or open InDesign and go to Help > About Adobe InDesign to view the exact version number.
    Affected if The displayed version is 15.1.1 or any version number lower than 15.1.1 (e.g., 15.0.x, 14.x, etc.)
  2. Check installed InDesign version on macOS
    Open Finder, navigate to Applications, right-click Adobe InDesign 2020 or later, select Get Info, and check the version field. Alternatively, open InDesign and go to Adobe InDesign > About Adobe InDesign.
    Affected if The displayed version is 15.1.1 or any version number lower than 15.1.1.
  3. Verify the specific version string in installation directory
    Check the version.xml or similar version file in the InDesign application installation directory (commonly C:\Program Files\Adobe\Adobe InDesign 2020\ on Windows or /Applications/Adobe InDesign 2020/ on macOS).
    Affected if The recorded version is 15.1.1 or earlier.

You are affected if InDesign version 15.1.1 or any earlier version (15.0.x, 14.x, etc.) is installed on the system, as these versions contain the vulnerable file parsing code for INDD files.
