How to fix it
Adobe DNG SDK is affected by CVE-2026-48267, a denial-of-service risk. DNG SDK versions 1.7.1 2536 and earlier are affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. The recommended remediation is to update to an Adobe DNG SDK release newer than 1.7.1 2536 that includes the APSB26-67 fix, or the vendor-supported fixed SDK release listed by Adobe. Until the update is complete, avoid opening untrusted DNG files and isolate DNG processing until patched, review logs, and reduce exposure of the affected service or workflow.
- Inventory every deployment, package, appliance, container, service, and managed environment that uses Adobe DNG SDK.
- Confirm the installed version and compare it with the affected versions listed in the source advisory and the source advisory for CVE-2026-48267.
- Apply the vendor-supported fix: update to an Adobe DNG SDK release newer than 1.7.1 2536 that includes the APSB26-67 fix, or the vendor-supported fixed SDK release listed by Adobe.
- If the update cannot be applied immediately, avoid opening untrusted DNG files and isolate DNG processing until patched; disable unnecessary public access, endpoints, integrations, uploads, management interfaces, or high-risk features until patched.
- Review application, device, reverse-proxy, WAF, package manager, container, authentication, and audit logs for activity related to CVE-2026-48267.
- Rotate sessions, API tokens, service credentials, integration keys, and administrator passwords if logs or affected data indicate compromise, code execution, credential exposure, or unauthorized access.
- Clear caches, restart affected services, rebuild affected containers or appliances when appropriate, and remove temporary files, stored payloads, generated artifacts, or unsafe configuration created during exploitation attempts.

- Confirm Adobe DNG SDK now reports an Adobe DNG SDK release newer than 1.7.1 2536 that includes the APSB26-67 fix, or the vendor-supported fixed SDK release listed by Adobe or a later vendor-supported fixed release for the deployed branch.
- Verify the affected workflow no longer allows the behavior described in CVE-2026-48267, using a safe regression test or vendor-provided validation method.
- Review logs after remediation for continued exploit attempts, denial-of-service symptoms, suspicious redirects, unauthorized requests, file access, credential exposure, or configuration changes.
- Rerun a Fixnx scan and any product-specific scanner, package audit, device health check, or manual regression test relevant to the affected service.
- Document affected assets, fixed versions, mitigation decisions, validation evidence, and any cleanup or credential rotation performed.
