CVE-2026-57212: CWE-770: Allocation of Resources Without Limits or Throttling in rabbitmq rabbitmq-server
CVE-2026-57212 is a high-severity vulnerability in rabbitmq-server affecting the rabbitmq_management HTTP API. Prior to versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the API improperly handles oversized valid JSON bodies on with_decode and direct_request paths due to incomplete size checks. This can lead to allocation of resources without limits or throttling, potentially impacting system stability. The issue is fixed in the specified versions.
AI Analysis
Technical Summary
RabbitMQ versions before 3.13.14, 4.0.19, 4.1.10, and 4.2.5 have a vulnerability in the rabbitmq_management HTTP API where the read_complete_body function checks the accumulated size of JSON payloads before the final chunk but not the final combined size. This allows oversized valid JSON bodies to be accepted on the with_decode and direct_request API paths, leading to uncontrolled resource allocation (CWE-770). The vulnerability is addressed in the fixed versions.
Potential Impact
The vulnerability allows an attacker with low privileges and no user interaction to send oversized JSON payloads to the rabbitmq_management HTTP API, causing resource allocation without limits or throttling. This can degrade system performance or cause denial of service conditions. There are no known exploits in the wild as of the published date.
Mitigation Recommendations
A fix is available in rabbitmq-server versions 3.13.14, 4.0.19, 4.1.10, and 4.2.5. Users should upgrade to one of these versions or later to remediate the vulnerability. No other mitigation or temporary workaround is indicated by the vendor advisory.
