Information disclosure via improper certificate validation

Published Oct 15, 2025 · Updated Oct 15, 2025

Improper certificate validation in Lenovo LeCloud Client 2.501.25.0 and earlier allows remote attackers to disclose client data. The CNA maps the flaw to the client's certificate-validation path but does not disclose the affected code or which certificate checks are missing. Exploitation requires a specific network condition and passive user interaction; the reported effect is information disclosure only.
