CVE-2026-558605.9 MED2.1%
——1MariaDB Connector/R2DBC is a non-blocking MariaDB and MySQL client implemented in Java. Prior to 1.4.1, org.mariadb:r2dbc-mariadb does not gate clear-text password authentication plugins on transport encryption because the AuthenticationPlugin interface has no capability for a plugin to require a secure connection. A hostile or man-in-the-middle MariaDB server can send an AuthSwitchRequest naming mysql_clear_password or dialog (PAM) over a plain-TCP unencrypted connection, and AuthenticationFlow permits ClearPasswordPluginFlow or PamPluginFlow to return the user's password as cleartext bytes on the wire. The disclosed credentials can subsequently be used to authenticate directly to the database server. This issue is fixed in version 1.4.1.6hCVE-2026-818363.7 BAJ8.4%
——3A vulnerability was detected in RooCodeInc Roo-Code up to 3.51.1. This vulnerability affects unknown code of the file src/integrations/claude-code/oauth.ts of the component OAuth Callback. The manipulation results in cleartext transmission of sensitive information. The attack may be performed from remote. A high complexity level is associated with this attack. It is stated that the exploitability is difficult. The exploit is now public and may be used. Multiple isses were reported to the vendor beforehand. They explain, that "they all apply to Roo Code, a project we no longer support - the repository was archived a while ago, and we don't encourage anyone to use it." This vulnerability only affects products that are no longer supported by the maintainer.3dCVE-2026-738097.5 ALT6.2%
——2A cleartext transmission of sensitive information vulnerability exists
in certain Ebyte gateway products. The web management interface does not
adequately protect sensitive communications using transport-layer
encryption. An attacker with access to network traffic could intercept
authentication or session-related information transmitted between a user
and the affected device. Successful exploitation could result in
disclosure of sensitive information and unauthorized access to device
management functionality.5hCVE-2026-696589.8 CRÍ14.8%
——4MQTT credentials and control traffic are transmitted in cleartext,
exposing sensitive information to network-level attackers. This may
enable unauthorized device impersonation and disruption of messaging
functions.5hCVE-2026-816917.5 ALT9.6%
——3openssl_encrypt versions before 1.4.9 fail to validate server URLs in login and register_with_email functions, accepting unencrypted http:// URLs and unconfigured hosts. Attackers on the network path can intercept cleartext credentials including client_id, passwords, and JWTs to achieve full keyserver account takeover.3dCVE-2026-198546.1 MED0.0%
——0When the ClickHouse plugin uses Native protocol (the default) with PDC or secure SOCKS, it asks for TLS but the connection library ignores that and talks to ClickHouse in the clear. Username, password, queries, and results can be read on the hop after the proxy. The server certificate is never checked, and a configured client certificate is not sent.2h
