CVE-2026-21353
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 2410 and earlier are affected by an Integer Overflow or Wraparound 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 confidenceThe DNG SDK versions 1.7.1 2410 and earlier contain an integer overflow vulnerability that can be triggered when processing a specially crafted malicious DNG (Digital Negative) image file. Successful exploitation allows arbitrary code execution in the context of the user who opens the file, requiring user interaction but no additional 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.
-
Identify software using the DNG SDKSearch for DNG-related DLLs or libraries on the system, such as dng_sdk.dll, libdng.a, or similar files. Check installed applications known to handle DNG image files (e.g., Adobe products, raw image processors, photo management software).Affected if Applications using DNG SDK to process DNG image files are present on the system
-
Determine the DNG SDK versionRight-click the identified DNG SDK library file and select Properties, then view the File Version or Product Version field. Alternatively, use a command like 'strings dng_sdk.dll | grep -i version' or check the application's About/Info dialog if it exposes SDK version details.Affected if The DNG SDK version is 1.7.1 2410 or earlier, or any version prior to 1.7.2
-
Verify DNG file processing capabilityCheck if the installed application can open and process DNG files. Attempt to open a DNG file or check file type associations in the system for .dng extension.Affected if The application can process DNG image files, making it a potential attack vector
-
Inspect for untrusted DNG file sourcesReview the system's default locations for downloaded or imported DNG files (e.g., Downloads folder, email attachments, imported from cameras). Check browser or email client download histories for .dng files from unverified sources.Affected if Untrusted or unknown DNG files from unverified sources exist on the system and may have been opened
You are affected if any application on your system uses a DNG SDK version earlier than 1.7.2 and processes DNG files, especially from untrusted sources, as exploitation requires user interaction to open a malicious DNG file.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.7.2
Update DNG SDK to a version beyond 1.7.1 2410 when a patch is released by Adobe. Until then, avoid opening untrusted or unknown DNG files from unverified sources.
DNG SDK 1.7.2 or later
- Identify all locations where the DNG Software Development Kit is used in your project dependencies or build configuration
- Update the DNG SDK dependency to version 1.7.2 or later in your package manager or build system (e.g., Maven, npm, NuGet, or direct binary reference)
- Verify the new SDK version (1.7.2+) is correctly resolved by checking dependency trees or manifests
- Rebuild your application ensuring the updated SDK is linked correctly
- Test the application to ensure image processing functionality works correctly with the updated SDK
- Redeploy the rebuilt application to all affected environments
