CVE-2026-24437

Local administrative-data disclosure via browser caching

Published Jan 26, 2026 · Updated Jan 26, 2026

Sensitive-data exposure in Tenda W30E V2 firmware 16.01.0.19(5037) and earlier allows local users to read cached administrative content. Administrative HTTP responses omit restrictive Cache-Control directives, so browsers retain credential-bearing pages in their local caches after access. A low-privileged local user who can access the browser cache can recover that content without modifying router configuration or interrupting service.
