CVE-2025-12047

Sensitive-file disclosure via improper certificate validation

Published Nov 12, 2025 · Updated Nov 12, 2025

Improper certificate validation in Lenovo Scanner Pro before 1.2.7 allows remote attackers on the same logical network to read sensitive user files. The published record identifies improper certificate validation but does not disclose the affected request path or how an untrusted certificate is accepted. Exploitation requires adjacent logical-network access and an undisclosed additional circumstance; the reported impact is limited to file confidentiality.
