keycloak-services: keycloak-services: Missing per-role authorization on RoleContainerResource composite endpoints

A flaw was found in the RoleContainerResource component of Keycloak. The issue occurs because certain name-based endpoints in the admin REST API do not properly enforce authorization checks when managing composite roles. This allows a delegated administrator with manage-realm permissions to remov...

keycloak-services: keycloak-services: SAML Redirect DEFLATE helpers leak native zlib state

A flaw was found in the SAML Redirect Binding implementation of Keycloak, an open-source identity and access management solution. The issue occurs because the custom DEFLATE compression and decompression helpers fail to release native zlib memory after use. An unauthenticated attacker can exploit...

react-router: React Router: Remote Code Execution via prototype pollution in Framework Mode

A flaw was found in React Router when operating in Framework Mode. A remote attacker could exploit an existing prototype pollution vulnerability within the application code. This could lead to unauthorized remote code execution RCE on the server through a two-step attack involving external...

keycloak-services: keycloak-services: Microsoft external access-token exchange bypasses configured tenant

Keycloak provides a way to let users log in using Microsoft accounts while restricting access to a specific organization tenant. A flaw was discovered where this restriction is ignored when using the token exchange feature. This means an attacker with a valid Microsoft token from a completely...

keycloak-services: keycloak-services: JWT Bearer authorization grant does not enforce consentRequired

A flaw was found in the JWT Bearer authorization grant implementation within the keycloak-services component of Red Hat Build of Keycloak. This component handles various OAuth2 and OpenID Connect grant types used for issuing access tokens. The issue occurs because the JWT Bearer grant fails to...

keycloak-services: keycloak-services: Privilege escalation via impersonation role allows takeover of realm administrator accounts

Keycloak is an open-source identity and access management solution. A vulnerability was discovered where a user with the impersonation role can impersonate a realm administrator. This allows the attacker to gain full administrative control over the realm, including the ability to manage users,...

keycloak-services: keycloak-services: Incorrect authorization in admin role-composite deletion allows delegated admin to remove privileged child roles

A flaw was found in the admin REST API of Keycloak, a solution for identity and access management. The issue occurs when a delegated administrator attempts to remove a child role from a composite role. Due to missing authorization checks, an attacker with limited administrative permissions can...

keycloak-services: keycloak-services: OIDC redirect_uri fragment bypass in HTTP parameter pollution check

A flaw was found in the keycloak-services component of Keycloak, which handles OpenID Connect OIDC authentication flows. The issue occurs because the security check designed to prevent HTTP parameter pollution only inspects the query portion of a redirect URL and ignores the fragment portion. Whe...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via AMQP frame size negotiation

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. A malicious or compromised AMQP broker can exploit this by advertising an extremely small frame size during connection negotiation. This can lead to excessive fragmentation of client publications, consuming significant CPU resources...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service due to synchronous event channel blocking

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. When the client synchronously sends events to application-provided channels, an unbuffered or full listener channel can cause the client's reader to block. This blockage prevents the processing of critical messages and heartbeats,...

go.opentelemetry.io/otel/sdk/log: OpenTelemetry-Go: Denial of Service via attacker-driven log emission

A flaw was found in the OpenTelemetry-Go BatchingProcessor component. A remote attacker can exploit this by sending a high volume of log emissions, which can fill the asynchronous export buffer. This causes the processor to enter a tight CPU loop, repeatedly retrying to export logs without proper...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Connection configuration overwrite via unsanitized TLS path parameter injection

A flaw was found in RabbitMQ amqp091-go. The URI.String function in uri.go concatenates TLS asset path values directly into an AMQPS query string without proper encoding. If an application processes a TLS asset path containing special characters like ampersand or equals delimiters, these can be...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via signed-to-unsigned integer casting

A flaw was found in RabbitMQ amqp091-go. The Channel.Qos function in channel.go incorrectly handles negative integer values for prefetchCount and prefetchSize, casting them to large unsigned integers. This allows an application that processes untrusted Quality of Service QoS configuration to...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Denial of Service via Malicious AMQP Field Length

A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send a specially crafted AMQP Advanced Message Queuing Protocol message with a malformed field length. This can cause an integer overflow, leading to a runtime panic in the client process. Consequently, the client...

github.com/rabbitmq/amqp091-go: RabbitMQ amqp091-go: Plaintext Credential Exposure via Exported PLAIN Authentication Fields

A flaw was found in RabbitMQ amqp091-go, a Go client for AMQP 0.9.1. This vulnerability allows plaintext credentials to be exposed. After a successful PLAIN authentication handshake, the client retains passwords in an unencrypted format within its connection configuration. Local code with access ...
