Incorrect access control in the component l_0_0.xml of TP-Link ARCHER-C7 v5 allows attackers to access sensitive information.

A permissive web security configuration may allow cross-origin restrictions enforced by modern browsers to be bypassed under specific circumstances. Exploitation requires the presence of an existing client-side injection vulnerability and user access to the affected web interface. Successful exploitation could allow unauthorized disclosure of sensitive information. Fixed in updated Omada Cloud Controller service versions deployed automatically by TP‑Link. No user action is required.

This vulnerability allows network-adjacent attackers to escalate privileges on affected installations of TP-Link TL-WA855RE Firmware Ver: 855rev4-up-ver1-0-1-P1[20191213-rel60361] Wi-Fi extenders. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the first-time setup process. The issue results from the lack of proper validation on first-time setup requests. An attacker can leverage this vulnerability to reset the password for the Admin account and execute code in the context of the device. Was ZDI-CAN-10003.

This vulnerability allows remote attackers to bypass authentication on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SSH port forwarding requests during initial setup. The issue results from the lack of proper authentication prior to establishing SSH port forwarding rules. An attacker can leverage this vulnerability to escalate privileges to resources normally protected from the WAN interface. Was ZDI-CAN-9664.

An authentication bypass vulnerability within the HTTP handling of the DS configuration service in TP-Link Tapo C520WS v2.6 was identified, due to inconsistent parsing and authorization logic in JSON requests during authentication check. An unauthenticated attacker can append an authentication-exempt action to a request containing privileged DS do actions, bypassing authorization checks. Successful exploitation allows unauthenticated execution of restricted configuration actions, which may result in unauthorized modification of device state.

A vulnerability in the TP-Link Archer c20 router with firmware version V6.6_230412 and earlier permits unauthorized individuals to bypass the authentication of some interfaces under the /cgi directory. When adding Referer: http://tplinkwifi.net to the the request, it will be recognized as passing the authentication. NOTE: this is disputed by the Supplier because the response to the API call is only "non-sensitive UI initialization variables."

Authentication bypass in the password recovery feature of the local web interface across multiple VIGI camera models allows an attacker on the LAN to reset the admin password without verification by manipulating client-side state. Attackers can gain full administrative access to the device, compromising configuration and network security.

On Tapo C520WS v2, restricted accounts (for example, hub users) are intended to execute only a limited set of low‑sensitivity operations. Due to a logic flaw in the device’s API authorization mechanism, an attacker can craft requests that leverage legitimate “method mapping” behavior to bypass whitelist restrictions, allowing restricted operations to be masked as permitted requests and executed. Successful exploitation may allow an attacker (with access to a restricted account) to execute unauthorized sensitive operations.  Depending on the operation invoked, impact could include device resets, unintended configuration changes, or disruption of normal operation, leading to loss of availability and integrity of the device.

The vendor was contacted early about this disclosure but did not respond in any way.

Authentication bypass in Netcomm router models NF20MESH, NF20, and NL1902 allows an unauthenticated user to access content. In order to serve static content, the application performs a check for the existence of specific characters in the URL (.css, .png etc). If it exists, it performs a "fake login" to give the request an active session to load the file and not redirect to the login page.

The web application exposed by the Canon Oce Colorwave 500 4.0.0.0 printer is vulnerable to authentication bypass on the page /home.jsp. An unauthenticated attacker able to connect to the device's web interface can get a copy of the documents uploaded by any users. NOTE: this is fixed in the latest version.

The fix for CVE-2026-28215 in version 2026.2.0 addresses the unauthenticated POST /v1/onboarding/config endpoint by checking onboardingCompleted and canReRunOnboarding before allowing config overwrites. However, GET /v1/onboarding/config still leaks all infrastructure secrets in plaintext to unauthenticated users when the ONBOARDING_RECOVERY_TOKEN stored in the database is an empty string. This vulnerability is fixed in 2026.4.0.

Authentication Bypass in cf-auth-proxy in Cloud Foundry Foundation all installations allows an unauthenticated remote attacker to gain read access to every log and metric for every application and platform component via minting a JWT that the cf-auth-proxy accepts as a valid logs.admin token.

Improper authentication in Azure SRE Agent allows an unauthorized attacker to disclose information over a network.

Passport-wsfed-saml2 is a ws-federation protocol and SAML2 tokens authentication provider for Passport. In versions prior to 4.6.3, a remote attacker may be able to bypass WSFed authentication on a website using passport-wsfed-saml2. A successful attack requires that the attacker is in possession of an arbitrary IDP signed assertion. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered. This issue is patched in version 4.6.3. Use of SAML2 authentication instead of WSFed is a workaround.
