CVE-2026-57212
Last modified
CVE-2026-57212 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. RabbitMQ is a messaging and streaming broker. Prior to 3.13.14, 4.0.19, 4.1.10, and 4.2.5, the rabbitmq_management HTTP API accepts oversized valid JSON bodies on with_decode and direct_request paths because read_complete_body checks the accumulated size before the final chunk but not the final combined size. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
