Executive ViewAI
Organizations using RT-Thread should be aware of moderate risk from CVE-2025-1115, a information exposure vulnerability rated CVSS 4.8. Sensitive information could be exposed to unauthorized parties. Proof-of-concept code is publicly available. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: restrict endpoint access, redact sensitive data in logs.
