CVE-2026-73253

A flaw was found in Mongoose. Wildcard certificate matching in its built-in Transport Layer Security TLS stack does not properly restrict matches to a single domain level. An on-path network attacker with a valid wildcard certificate for a parent domain could exploit this flaw to bypass hostname...

CVE-2026-93601
