CVE-2026-47964
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 · uneditedDNG SDK versions 1.7.1 2536 and earlier are affected by a Heap-based Buffer Overflow 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 · high confidenceHeap-based buffer overflow in DNG SDK versions 1.7.1 2536 and earlier allows arbitrary code execution when a user opens a maliciously crafted DNG image file. The vulnerability operates in the context of the current user process.

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 DNG SDK library filesSearch for files named 'dng_sdk.dll', 'dngsdk.dll', or similar DNG-related DLLs on the system using file search or PowerShell command: Get-ChildItem -Path C:\ -Recurse -Filter 'dng*.dll' 2>$nullAffected if DNG SDK library files are found on the system
-
Identify installed DNG SDK versionRight-click the located DNG library file, select Properties, then view the File Version or Product Version field in the Details tabAffected if The version number is lower than 1.7.1.2611 (or shows 1.7.1 2536 or earlier)
-
Check for applications embedding DNG SDKReview installed software that handles DNG image files (digital asset management tools, photo editors, RAW processors). Look for vendor information referencing Adobe DNG SDK in application about/details pagesAffected if An application using Adobe DNG SDK is installed and processes DNG files
-
Determine if untrusted DNG processing is enabledReview application settings for handling DNG files from external or untrusted sources. Check if file type validation or sandboxing is implemented for DNG file processingAffected if Applications process DNG files without adequate validation or sandboxing for files from untrusted sources
The environment is affected if any application embeds Adobe DNG SDK with version lower than 1.7.1.2611 and processes DNG files from untrusted sources.

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 · scoped1.7.1.2611
Update DNG SDK to a version beyond 1.7.1 2536; implement file type validation and sandboxing for DNG file processing; advise users against opening untrusted DNG files.
DNG SDK version 1.7.1.2611 or later
- 1. Identify all applications or tools that integrate the Adobe DNG Software Development Kit
- 2. Locate the DNG SDK library files (dng_sdk.lib, dng_sdk.dll, or dng_host.cpp depending on integration method) in your project dependencies
- 3. Verify the current version of the DNG SDK being used (check library version metadata or project dependency manifests)
- 4. Download the updated DNG SDK version 1.7.1.2611 or later from the official Adobe source at helpx.adobe.com
- 5. Replace the old DNG SDK files with the new version 1.7.1.2611 files in your project
- 6. Rebuild and recompile any projects that link against the DNG SDK
- 7. Test the rebuilt application to ensure DNG image processing functionality works correctly
- 8. Redeploy the updated application to all affected environments
