Improper input validation in Samsung Email prior to version 6.2.13.1 allows local attackers to create arbitrary files within the application sandbox.
AnalysisAI
Improper input validation in Samsung Email prior to version 6.2.13.1 enables local attackers to create arbitrary files within the application's Android sandbox, affecting integrity and availability of the email client. The attack is confined to the Samsung Email sandbox by Android's isolation model and cannot directly escalate to system-level or cross-application impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the target Samsung Android device - either physical access or the ability to execute code locally, such as via a co-installed malicious application. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.1 with AV:L accurately reflects the local-only nature of this vulnerability and is consistent with the description. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A malicious application installed on the same Samsung Android device crafts input specifically designed to bypass Samsung Email's input validation, causing the email client to write attacker-specified files into its application sandbox. This could allow the malicious app to overwrite email configuration or cache files, potentially disrupting service or injecting malicious data that the email client later processes. |
| Remediation | Update Samsung Email to version 6.2.13.1 or later - this is a vendor-released patch confirmed by Samsung's security team (mobile.security@samsung.com) and the EUVD entry. … Detailed patch versions, workarounds, and compensating controls in full report. |
