Published: 10 March 2026
Summary
CVE-2026-27280 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Adobe Dng Software Development Kit. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 1.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires timely patching and remediation of the out-of-bounds write flaw in the DNG SDK as recommended in Adobe's security bulletin.
Provides memory protections such as non-executable memory and stack guards that mitigate exploitation of out-of-bounds writes leading to arbitrary code execution.
Mandates validation of untrusted DNG file inputs to block malformed data that triggers the out-of-bounds write during processing.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds write in DNG file parser enables arbitrary code execution on client when victim opens malicious file (T1203 Exploitation for Client Execution + T1204.002 Malicious File).

Deeper analysisAI
CVE-2026-27280 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe DNG SDK versions 1.7.1 build 2471 and earlier. The flaw occurs during processing of DNG files and can lead to arbitrary code execution in the context of the current user. It has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high impact with low attack complexity but requiring local access and user interaction.
Exploitation requires an attacker to deliver a specially crafted malicious DNG file to a victim, who must then open it using an affected application leveraging the DNG SDK. No special privileges are needed (PR:N), and successful exploitation allows arbitrary code execution with the privileges of the current user, potentially enabling full system compromise on the victim's machine.
The official Adobe security bulletin APSB26-30, available at https://helpx.adobe.com/security/products/dng-sdk/apsb26-30.html, provides details on the vulnerability, affected versions, and recommended mitigations, including updates to patched versions of the DNG SDK.
