DescriptionCVE.org

When the RabbitMQ management aliveness check fails, the configured admin password is embedded in cleartext in the thrown exception message. Spring AMQP 4.1.0 Spring AMQP 4.0.0 - 4.0.4 Spring AMQP 3.2.0 - 3.2.12 Spring AMQP 2.4.18 and earlier

AnalysisAI

Cleartext credential exposure in Spring AMQP affects applications that use the RabbitMQ management aliveness check: when that check fails at runtime, the configured admin password is embedded verbatim in the thrown Java exception message, making it visible to anyone with access to exception output. The vulnerability spans multiple major release lines - 2.4.x, 3.2.x, and 4.0.x through 4.1.0 - and was reported by security@vmware.com, the Spring Security team. …

Vulnerability AssessmentAI

Exploitation The Spring AMQP application must be explicitly configured to use the RabbitMQ management aliveness check - this is not enabled by default and requires the developer to configure the RabbitMQ management HTTP endpoint URL and admin credentials within the application. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 5.3 Medium with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N reflects a narrowly scoped but meaningful confidentiality-only risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Patch availability per vendor advisory - exact fixed version numbers for each release line are not confirmed from the provided input data; the Spring security advisory at https://spring.io/security/cve-2026-59271 must be consulted for authoritative fixed versions before upgrading. … Detailed patch versions, workarounds, and compensating controls in full report.
