Published Jun 5, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description

Analysis

AI-generated

Technical impact

This vulnerability is caused by insufficient validation of user-supplied URLs. A malicious payload can be supplied from within the device, causing the application to open a URL scheme that launches any desired activity under Samsung Members' privileges. The attack remains confined to the application’s trust boundary and does not elevate privileges beyond those granted to Samsung Members.

Affected Systems

Samsung Mobile's Samsung Members application, all versions prior to 5.8.01.5. The issue is local, affecting only devices that already have the vulnerable app installed.

Risk and Exploitability

The CVSS score of 6.9 indicates moderate severity. The EPSS score of <1% indicates a very low but nonzero exploitation probability, and the vulnerability is not listed in CISA’s KEV catalog, suggesting limited known exploitation. The likely attack vector is local, requiring the attacker to have physical or local remote access to the device; no external network-based attack is noted in the description.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Samsung Members to version 5.8.01.5 or later, which contains input validation fixes
  • If an immediate update is not possible, consider uninstalling or disabling Samsung Members to eliminate the local threat surface
  • Monitor device logs for unexpected activity launches and apply any additional device monitoring or permissions restrictions recommended by Samsung
