CVE-2026-7036
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 · uneditedA vulnerability was identified in Tenda i9 1.0.0.5(2204). This vulnerability affects the function R7WebsSecurityHandlerfunction of the component HTTP Handler. The manipulation leads to path traversal. Remote exploitation of the attack is possible. The exploit is publicly available and might be used.
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 · high confidenceA path traversal vulnerability exists in Tenda i9 router firmware version 1.0.0.5(2204), specifically in the HTTP Handler component's R7WebsSecurityHandlerfunction. This allows remote attackers to access files outside the web root directory via specially crafted HTTP requests. The CVSS 9.8 score indicates trivial network exploitation with no authentication required.

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 i9 router on your networkLocate the device by MAC address, network inventory, or access the router admin interface and check the model information page typically found under System or Status settingsAffected if The device model is Tenda i9
-
Check installed firmware versionLog into the router web interface, navigate to System Settings or Firmware Upgrade section, and record the firmware version number displayedAffected if The firmware version shown is 1.0.0.5(2204)
-
Verify HTTP service accessibilityAttempt to access the router login page via HTTP on the default Tenda web port (usually port 80) from a network-connected hostAffected if The HTTP administration interface is reachable on the network
-
Confirm vulnerable component presenceSince the vulnerability exists in the R7WebsSecurityHandler function of the HTTP Handler, the only definitive check is matching the exact affected firmware version from step 2Affected if Running firmware is exactly version 1.0.0.5(2204)
You are affected only if you have a Tenda i9 router running firmware version 1.0.0.5(2204) with its HTTP administration interface accessible on your network.

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 dataApply vendor firmware update when available; until then, restrict administrative interface access to trusted networks only via firewall rules or VPN, as the exploit is publicly available.
