CVE-2026-24439Network attack vector

Script execution via missing MIME-type enforcement

Published Jan 26, 2026 · Updated Jan 26, 2026

Missing MIME-type enforcement in Tenda W30E V2 through V16.01.0.19(5037) allows remote attackers to execute script in browsers. The web management interface omits the X-Content-Type-Options: nosniff response header, so browsers can MIME-sniff attacker-influenced content as executable script. Exploitation requires an attacker-influenced management response and a browser that sniffs its type; configuration changes and service interruption are not established.
