Technical description

An Improper Authentication vulnerability in the Apache Doris Frontend (FE) meta service allows an unauthenticated remote attacker to access internal metadata service endpoints. The affected endpoints relied on client-supplied node information for authentication without providing sufficient authentication of the requesting party. Under certain network configurations, a remote attacker may be able to bypass the intended access control and access internal FE metadata interfaces, potentially exposing sensitive cluster information. This issue affects Apache Doris: from 2.0.0 through 2.0.*, from 2.1.0 through 2.1.*, from 3.0.0 through 3.0.*, from 3.1.0 through 3.1.*, from 4.0.0 before 4.0.8, and from 4.1.0 before 4.1.4. Versions 1.2.x and earlier are not affected by this header-trust vulnerability. Users are recommended to upgrade to a fixed release (4.0.8 or 4.1.4), which fixes the issue.

———A flaw was found in the Conditional OTP authenticator of Keycloak, an identity and access management solution. The issue occurs when the system evaluates specific HTTP headers to determine if a one-time password (OTP) should be skipped, but fails to verify if those headers came from a trusted source. This could allow an attacker who already has a user's password to bypass the second-factor authentication by providing a specially crafted header in their request.4h CVE-2026-75973—

———Improper Authentication vulnerability in Apache Tomcat. When Jakarta Authentication was configured with SimpleAuthConfigProvider as the default provider and multiple web application used that provider, the realm for the first web application to authenticate a request would be used for all web applications. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.25, from 10.1.0-M1 through 10.1.59, from 9.0.0.M4 through 9.0.121. The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100. Other unsupported versions may also be affected. Users are recommended to upgrade to version 11.0.26, 10.1.60, 9.0.122, which fixes the issue.4h CVE-2026-964566.3 MED

———The Reachy Mini Bluetooth service asks a connecting device for a PIN before it will accept commands. The check protects the session but not the caller, so an attacker in Bluetooth range can ride along on someone else's successful authentication. The authenticated state is kept in a single shared flag on the service instance rather than per device. BlueZ passes the calling device's identity to the characteristic write handler in the options argument, but WriteValue(self, value, options) in src/reachy_mini/daemon/app/services/bluetooth/bluetooth_service.py ignores options entirely. The handler therefore has no idea which device sent a given write, and it cannot tell the authenticated one from any other. Once any device completes the PIN exchange, the flag is set and every nearby device can send CMD_ commands until it resets. An attacker simply waits within radio range for a legitimate user to authenticate, then writes commands into the same window. No PIN is ever guessed or brute-forced. This is the second step of a three-step chain that JFrog documented against the robot. The first is the unrestricted file upload in the media sounds API, tracked as CVE-2026-55419, which places an attacker-controlled script on the filesystem. This issue then provides command access over Bluetooth. The third is the Bluetooth command handler path traversal, tracked as CVE-2026-62661, which runs that script as root.5h CVE-2026-828439.0 CRI
