Lifecycle Timeline
3Description
Storage credentials are hardcoded in the mobile app and device firmware. These credentials do not adequately limit end user permissions and do not expire within a reasonable amount of time. This vulnerability may grant unauthorized access to production storage containers.
Analysis
Hardcoded storage credentials in Gardyn mobile application and device firmware grant unauthenticated remote attackers access to production cloud storage containers with excessive permissions. The CVSS v4.0 score of 8.8 reflects network-accessible attack vector with no complexity barriers, enabling high confidentiality impact and limited integrity/availability impact. CISA ICS-CERT disclosure indicates industrial/IoT context. No public exploit identified at time of analysis, though hardcoded credential vulnerabilities are trivial to exploit once discovered. EPSS data not available for this recent CVE.
Technical Context
This vulnerability exemplifies CWE-798 (Use of Hard-coded Credentials), a critical authentication antipattern where static credentials are embedded directly in application binaries or firmware images. The Gardyn mobile application and associated device firmware contain plaintext or weakly obfuscated cloud storage access credentials that cannot be rotated without firmware/app updates. These credentials authenticate to backend storage containers (likely AWS S3, Azure Blob, or similar) with overly permissive IAM policies, violating the principle of least privilege. The credentials lack time-based expiration, creating a permanent authentication bypass. Reverse engineering mobile applications (.apk/.ipa files) or extracting firmware images trivially exposes these credentials, as they must be readable by the application runtime. The CPE strings identify Gardyn mobile application and cloud API as affected components, suggesting a smart gardening IoT ecosystem where both edge devices and mobile clients share the same hardcoded backend credentials.
Affected Products
Gardyn mobile application (all versions prior to patched release) identified by CPE cpe:2.3:a:gardyn:mobile_application, and Gardyn cloud API (all versions) identified by CPE cpe:2.3:a:gardyn:cloud_api are affected. The vulnerability spans both the consumer-facing mobile application available on iOS and Android platforms, and the underlying device firmware that connects Gardyn smart indoor gardening systems to cloud infrastructure. Specific version ranges are not provided in available data, suggesting all deployed versions contain the hardcoded credentials until vendor remediation. Official vendor security advisory available at https://mygardyn.com/security/ and detailed technical analysis in CISA advisory ICSA-26-055-03 at https://www.cisa.gov/news-events/ics-advisories/icsa-26-055-03.
Remediation
Primary remediation requires updating to patched versions of the Gardyn mobile application and device firmware that remove hardcoded credentials and implement proper authentication mechanisms such as OAuth 2.0, per-device unique credentials, or short-lived STS tokens. Specific patched version numbers are not confirmed from available data; consult the vendor security advisory at https://mygardyn.com/security/ for release information. Backend mitigation requires immediate rotation of the compromised storage credentials and implementation of least-privilege IAM policies with time-based session tokens. Organizations should invalidate existing hardcoded credentials in cloud storage access policies and deploy credential rotation infrastructure. As an interim workaround, network-level controls such as IP allowlisting on storage bucket policies may reduce exposure, though this does not address the root vulnerability. Review CISA advisory ICSA-26-055-03 at https://www.cisa.gov/news-events/ics-advisories/icsa-26-055-03 and the CSAF document at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-055-03.json for comprehensive mitigation guidance.
