CVE-2026-10562
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 · uneditedAn unauthenticated URL redirection vulnerability has been identified in Archer AX20 V2 due to improper validation of user-supplied URL input within the web interface. An unauthenticated attacker can craft URLs containing URL-encoded path traversal sequences. When processed by the embedded web server, these inputs may cause the device to respond with HTTP 3xx redirects to attacker-controlled external domains. This issue affects Archer AX20 V2.0: through 2.1.9 Build 20230829.
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 confidenceThe Archer AX20 V2 router web interface fails to properly validate user-supplied URL parameters, allowing URL-encoded path traversal sequences to bypass filters. An unauthenticated attacker can craft malicious URLs that cause the device's embedded web server to issue HTTP 3xx redirects to attacker-controlled external domains, enabling phishing attacks.

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.
-
Confirm router modelLog into the router admin interface or check the device label/metadata to verify the exact model is Archer AX20 V2Affected if The device is not an Archer AX20 V2 model, then this specific CVE does not apply
-
Identify firmware versionAccess router admin panel, look for Firmware Version under System or Administration settings, or check via `tp-link` command-line tools if availableAffected if Firmware version is unknown or cannot be determined, assume potential exposure since patches are pending
-
Verify web interface is enabledCheck router settings for 'Remote Management' or 'Web Management' under Administration or Advanced settings to confirm the HTTP/HTTPS web interface is accessibleAffected if Web interface is disabled and router is not accessible externally, exposure is significantly reduced
-
Check for external access to web interfaceDetermine if the router web interface is exposed to WAN/internet by checking if remote management is enabled or by testing external connectivity on ports 80/443Affected if The web interface is accessible from the internet (WAN), the device is at higher risk from unauthenticated attack attempts
If the device is an Archer AX20 V2 with web interface enabled and potentially accessible, it may be affected; contact TP-Link for firmware update availability to confirm fix status.

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 dataContact TP-Link for available firmware updates; until a patch is released, warn users not to click untrusted links and consider network segmentation to limit exposure from this open redirect.
