remote code execution when Mesh mode is enabled. This
may result in high impact to the confidentiality, integrity, and availability
of the affected device.
A hard-coded
cryptographic key vulnerability exists in the web module of TP-Link Archer
AX55 v4. A LAN attacker who captures an HTTP login session may use the known
shared RSA private key to decrypt the administrator password; the
weakened AES session key further reduces the effort required to
compromise session confidentiality.
Successful
exploitation may disclose the administrator password captured from an HTTP
login session and compromise session confidentiality.
A pre-authentication stack-based buffer overflow vulnerability exists in the http_gdpr_decrypt function of TL-MR100 V3.20 due to insufficient bounds checking of encrypted requests to the /cgi/login endpoint. An adjacent unauthenticated attacker with access to the router's web management interface can trigger memory corruption and potentially achieve arbitrary code execution.
Successful exploitation can overwrite saved control-flow data on the httpd process stack prior to authentication, resulting in a service crash or potential arbitrary code execution in the context of the affected process.
TP-Link Kasa smart home devices HS103P3 and HS103P4 v5 have insufficient cryptographic protections in their local communication protocol. This weakness allows an adjacent network attacker to intercept, replay, or forge control messages. Exploitation can lead to unauthorized control of the device, causing state changes, disruption, or denial of service.
A stored OS
command injection vulnerability exists in the parent-control module of TP-Link
Archer BE3600 V1. An authenticated adjacent attacker with administrative access
may store a crafted profile name containing shell metacharacters, which is
later processed unsafely during daily cloud report generation and may result in
arbitrary command execution.
Successful
exploitation may allow command execution on the affected device with potential
impact to device confidentiality, integrity, and availability.
An authenticated command injection vulnerability in TP-Link Archer BE800 V1 allows an attacker with administrative access to execute arbitrary system commands with root privileges by injecting shell metacharacters via a VPN connection.
Successful exploitation may enable persistent backdoors, credential theft, LAN reconnaissance, and router-assisted attacks against connected devices.
An unauthenticated OS command injection vulnerability exists in the parental control functionality of Archer BE800 V1, BE3600 V1, and AX75 V1 due to improper filtering and neutralization of special characters in certain parameters. A LAN-based attacker can inject arbitrary commands and execute them with root privileges.
Successful exploitation may result in complete device compromise and impact the confidentiality, integrity, and availability of the affected device and network traffic.
The use of
hard-coded cryptographic key vulnerability has been identified in the mesh
functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6.
A shared RSA-512 mesh group private key is present in the affected
firmware and is used by the mesh protocol for node authentication. An attacker who obtains the firmware image
and has local network access may be able to authenticate as a mesh node without
possessing a device-specific credential.
Successful
exploitation may allow an unauthenticated adjacent attacker to impersonate a
trusted mesh node and bypass mesh node authentication, which may permit unauthorized
changes to device or mesh configuration, affecting confidentiality, integrity
and availability.
A
stack-based out-of-bounds write vulnerability exists in the login request
handling functionality of the administrative web interface of TP-Link TL-MR6400 v7 routers. An unauthenticated adjacent attacker can trigger the vulnerability
by sending a specially crafted malformed HTTP request.
Successful
exploitation may cause the web service process to crash, resulting in a
denial-of-service condition and temporary loss of access to the router's web
management interface.
A NULL
pointer dereference vulnerability exists in the HTTP request parsing
functionality of
TL-MR6400 v7. An unauthenticated remote attacker can
trigger the vulnerability by sending a specially crafted HTTP request
containing a malformed session cookie header.
Successful
exploitation may cause the HTTP service process to crash, resulting in a
denial-of-service condition and temporary loss of management or CGI
functionality until service recovery.
CVE-2026-17250 is a stack-based buffer overflow vulnerability in the firmware update functionality of TP-Link TL-MR6400 version 7.0. It arises from unsafe handling of attacker-controlled metadata within a firmware image. Exploitation requires authentication and can lead to memory corruption and arbitrary code execution on the device. The vulnerability has a high severity score of 8.5. No patch or official fix information is currently provided.
A vulnerability exists in the Dynamic DNS (DDNS) functionality of TP-Link Omada Gateways. During communication with a third-party DDNS service, authentication credentials are transmitted over an unencrypted channel. An attacker who can observe or manipulate traffic between an affected device and the DDNS service may obtain sensitive authentication information or interfere with DDNS update operations. Exploitation requires DDNS to be configured, communication with an external DDNS service, and attacker visibility or control of the relevant network path.
Successful exploitation may result in disclosure of DDNS account credentials, unauthorized access to DDNS management functionality, or modification of DNS records associated with the affected deployment.
CVE-2026-19586 is a critical OS command injection vulnerability in TP-Link ER7212PC v2 devices configured as OpenVPN servers. It allows unauthenticated remote attackers to execute arbitrary commands by sending crafted input during OpenVPN connection establishment before authentication. Exploitation requires the OpenVPN Server feature to be enabled and reachable by the attacker. Successful exploitation could lead to full device compromise.
An unauthenticated attacker with network access to the captive portal service of an affected device can terminate active captive portal sessions, including forcing logout of specific users or clearing all active sessions. Affected users must re-authenticate to regain access.
Successful exploitation may allow termination of individual or all active captive portal sessions, causing temporary service disruption and requiring users to re-authenticate.
