Descripción técnica

utcp-mcp (the MCP plugin of python-utcp) through 1.1.2 connects to the HTTP and WebSocket MCP server URLs given in a call template's mcpServers configuration without the ensure_secure_url validation that the HTTP-family plugins apply, so the HTTPS/WSS-or-loopback rule is not enforced. A call template naming a plain-HTTP, non-loopback MCP server URL is dialed as configured, exposing the MCP handshake to network interception and permitting cleartext connections to internal hosts. The mcpServers configuration is operator-authored rather than remote data, and the connection is an MCP handshake rather than an arbitrary request returning a body, which limits practical exploitation; the OAuth2 token_url credential path described in the original report was not reachable in the affected versions, because the OAuth2 handler was never invoked and the call template's auth field was not read. Fixed in utcp-mcp 1.1.3, which validates server URLs before any connection is made.

——3A weakness has been identified in Tenda F6 12.02.01.73. Affected is an unknown function of the component Web Management Interface. Executing a manipulation of the argument ecos_pw can lead to cleartext transmission of sensitive information. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is told to be difficult. The exploit has been made available to the public and could be used for attacks.2d CVE-2026-1115948.1 ALT

——1HCL AppScan Azure Boards Plugin is affected by a Cleartext Transmission of Sensitive Information vulnerability when configured to communicate with the AppScan server over HTTP. This could allow an attacker to intercept credentials or authentication tokens during transmission. The plugin has been updated to display a warning when HTTP is used and recommend HTTPS for secure communication.3d CVE-2026-539865.3 MED

——4Girafit camera app (Android and iOS) version 1.9.1 and earlier, and Girafit camera devices, contain a hardcoded credentials vulnerability that allows attackers to obtain the shared TURN relay username by decompiling the app or intercepting unencrypted network traffic during live view registration. Attackers can extract the static TURN username and session token, which are identical across all installs and not tied to any user or device, potentially enabling tracking, impersonation, or further exploitation if combined with the TURN relay password.4d CVE-2026-1076924.8 MED

——1The War Thunder game client transmits its authentication bearer token (auth_jwt) in the very first data packet after the TCP handshake, using only LZ4 compression rather than encryption. An attacker positioned on the network path can passively intercept and decompress this packet to reveal the plaintext JSON payload. This vulnerability allows for temporary authenticated impersonation, enabling an attacker to access game services and certain user data (such as email address and displayed phone number) as the affected user. While this allows for unauthorized access to gameplay, it does not facilitate full account takeover, as it cannot be used to modify account security settings, change passwords, bypass two-factor authentication for account management, or access financial information.5d CVE-2026-151027.5 ALT
