The Bottom Line: RabbitMQ deployments are threatened by multiple remotely exploitable vulnerabilities that enable DoS, authorization bypass, and data compromise.
The messaging system RabbitMQ contains multiple vulnerabilities that allow remote attackers to conduct DoS attacks, bypass authorization boundaries, and manipulate or exfiltrate data.
According to the Federal Office for Information Security (BSI), the messaging system RabbitMQ contains multiple vulnerabilities that can be exploited by remote, anonymous attackers without prior authentication.
The identified vulnerabilities enable various attack scenarios: denial-of-service attacks to disrupt the service, circumvention of authorization mechanisms and tenant boundaries in multi-tenant environments, unauthorized manipulation or disclosure of data, and execution of cross-site scripting (XSS) attacks.
CISOs are required to promptly review the RabbitMQ versions in their own infrastructure. The impact depends on the respective vulnerability and the specific deployment configuration. Particularly critical are scenarios in which RabbitMQ is deployed in multi-tenant systems or is accessible directly from untrusted networks.
Current information on affected versions and patches is available in the BSI Security Notice WID-SEC-2026-2485. Timely patch management is recommended.
