CVE-2025-30318
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 · uneditedInDesign Desktop versions ID19.5.2, ID20.2 and earlier are affected by an out-of-bounds write 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 · moderate confidenceAdobe InDesign Desktop versions ID19.5.2, ID20.2 and earlier contain an out-of-bounds write vulnerability that allows arbitrary code execution when a user opens a specially crafted malicious file. The vulnerability exploits memory handling during file parsing, enabling an attacker to execute code in the context of the current user's privileges.

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.
-
Locate InDesign installation directoryOpen File Explorer and navigate to C:\Program Files\Adobe or C:\Program Files (x86)\Adobe. Look for folders named 'Adobe InDesign' followed by a version year (e.g., 'Adobe InDesign 2024' or 'Adobe InDesign 2025').Affected if No InDesign folder is found means the product is not installed.
-
Find the InDesign executableWithin the Adobe InDesign installation folder, locate InDesign.exe. The file is typically named 'InDesign.exe' in the main folder.Affected if The executable exists in a folder with a version year in the name.
-
Check InDesign version numberRight-click InDesign.exe, select Properties, then go to the Details tab. Look for the 'Product version' or 'File version' field. Alternatively, open InDesign and go to Help > About InDesign to display the exact version number.Affected if Version is 19.5.2 or earlier, OR version is 20.0 through 20.2 (any version less than 20.3 but at least 20.0).
-
Verify affected version rangeCompare your found version to these vulnerable ranges: version 19.x less than 19.5.3, or version 20.x less than 20.3. Note that version 19.5.3 and version 20.3 are the fixed releases.Affected if Your installed version falls within < 19.5.3 or >= 20.0 and < 20.3.
If Adobe InDesign Desktop is installed and the version is 19.5.2 or earlier, or between 20.0 and 20.2, the environment is vulnerable to this CVE when opening untrusted InDesign 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.
dbcve · scoped19.5.320.3
Apply the vendor security update from Adobe when available. Until then, enforce strict policies: do not open InDesign files from untrusted or unknown sources, disable file preview handlers, and consider using application sandboxing or virtualization for handling untrusted documents.
Adobe InDesign 19.5.3 or later, or Adobe InDesign 20.3 or later
- 1. Close Adobe InDesign if it is currently running
- 2. Open Adobe Creative Cloud desktop application or navigate to https://creativecloud.adobe.com
- 3. Locate Adobe InDesign in your installed applications
- 4. Click on the update or install button next to InDesign
- 5. Wait for the update to download and install completely
- 6. Verify the installed version by opening InDesign and checking Help > About Adobe InDesign
- 7. Confirm the version number is 19.5.3 or later, or 20.3 or later
