A potential command injection vulnerability was reported in the Tianxi AI Agent PC Application, distributed exclusively in the Chinese market, that could allow operating system commands to be executed if a local user opens a specially crafted link that is handled by the application.
AnalysisAI
Command injection in Lenovo's Tianxi AI Agent PC Application allows a local user, tricked into opening a specially crafted link, to execute arbitrary operating system commands on the affected machine. The vulnerability is rooted in inadequate sanitization of link content that the application processes through what is likely a registered URI scheme or deep-link handler. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the Tianxi AI Agent PC Application to be installed and running on the victim's machine, with its URI scheme or link handler registered and active with the operating system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.4 reflects a serious but interaction-dependent flaw: the AV:L/UI:A combination means exploitation requires the victim to be on the local machine and actively open a crafted link, significantly reducing automated or mass-exploitation potential compared to a network-reachable, no-interaction vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the Lenovo iKnow advisory at https://iknow.lenovo.com.cn/detail/442249 for the vendor-released patch and exact fixed version, as no specific remediation version is enumerated in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all Lenovo Tianxi AI Agent PC Application installations and isolate affected systems from sensitive network segments; issue an urgent user advisory warning against opening untrusted links and disable the application's URI scheme handler if possible. …
