RabbitMQ

Adversaries may perform rapid multi-queue purges in AMQP-based messaging systems, such as RabbitMQ, to facilitate data destruction or cause widespread application disruption following credential compromise.

A remote, authenticated attacker can exploit multiple undisclosed vulnerabilities in RabbitMQ to conduct denial-of-service attacks and bypass existing security measures, impacting the availability and integrity of messaging systems.

CVE-2026-63030 is a critical unauthenticated remote code execution vulnerability affecting WordPress Core versions 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1, allowing an unauthenticated attacker to execute arbitrary code via the WordPress REST API batch endpoint, potentially leading to complete website compromise.

CVE-2026-57217 details a vulnerability in RabbitMQ where topic authorization can be bypassed, leading to cross-tenant routing-key bypass, potentially allowing unauthorized access to or manipulation of routing keys in a multi-tenant environment.

CVE-2026-57219 describes an unauthenticated disclosure vulnerability in RabbitMQ, allowing an attacker to obtain OAuth client credentials via an HTTP API endpoint when RabbitMQ is configured with certain less common OAuth 2 configurations, potentially leading to unauthorized access to other systems or services.

CVE-2026-44839 is a cross-site scripting (XSS) vulnerability in the RabbitMQ management UI that arises from unsanitized virtual host (vhost) names, potentially allowing an attacker to execute arbitrary JavaScript in the context of a user's browser.
