CVE-2026-24427
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedShenzhen Tenda AC7 firmware version V03.03.03.01_cn and prior expose sensitive information in web management responses. Administrative credentials, including the router and/or admin panel password, are included in plaintext within configuration response bodies. In addition, responses lack appropriate Cache-Control directives, which may permit web browsers to cache pages containing these credentials and enable subsequent disclosure to an attacker with access to the client system or browser profile.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Tenda AC7 router firmware (V03.03.03.01_cn and prior) includes administrative credentials in plaintext within web management configuration responses. Additionally, responses lack Cache-Control headers, allowing browsers to cache pages containing these credentials and exposing them to attackers with access to the client system or browser profiles.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Tenda AC7 firmware versionAccess the router web interface and navigate to System Settings > Firmware Version, or check the footer of any admin page for the firmware build numberAffected if Firmware version is 03.03.03.01 or lower (e.g., 03.03.02.xx, 03.03.01.xx)
-
Inspect web configuration response for plaintext credentialsUse browser developer tools or a proxy to capture an HTTP response from the router's admin interface (e.g., when loading system status or admin settings pages). Examine the response body for visible username and password fields in clear textAffected if The HTTP response contains administrative username and password in plaintext rather than masked or hashed values
-
Check HTTP response headers for Cache-ControlIn browser developer tools Network tab, examine HTTP response headers from the router admin pages. Look specifically for the Cache-Control headerAffected if Cache-Control header is absent from HTTP responses, or present but missing 'no-store' and 'no-cache' directives
-
Verify browser cache contains sensitive dataCheck browser cache files (or use browser history) for previously accessed router admin pages. On shared或多用户 systems, examine cached files in the browser profile directoryAffected if Router admin pages are found in browser cache, exposing credentials in cached content
A Tenda AC7 router is affected if it runs firmware version 03.03.03.01 or lower AND the web interface responses contain plaintext admin credentials AND lack proper Cache-Control headers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched firmware version once released by Tenda. Additionally, configure the web server to include proper Cache-Control: no-store, no-cache headers to prevent credential caching.
