Improper access control in Galaxy Watch prior to SMR Apr-2025 Release 1 allows local attackers to access sensitive information of Galaxy wat

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Severity is disputed: the assigning authority (CNA) scores it 4.0, NVD 6.2.

Low priority for now. Update when a fix is released; follow the vendor's advisory.
