CVE-2025-2190Network attack vector

Code injection via mismatched-host certificate acceptance

Published Mar 11, 2025 · Updated Sep 9, 2025

Improper certificate validation in TECNO Mobile Palm Store 9.1.0 before 9.2.6 allows man-in-the-middle attackers to inject code. The com.transsnet.store client accepts a server certificate that is not associated with the requested host, but TECNO has not disclosed the affected request path or comparison logic. Exploitation requires a network position that permits traffic interception and a mismatched-host certificate; the published consequence is code injection.
