A remote unauthenticated actor, via prompt injection, may obtain Amazon MQ for RabbitMQ broker credentials or OAuth access tokens sent to a crafted endpoint controlled through a broker hostname introduced in the MCP client context. The CNA, AMZN, rates it CVSS 4.0 7.1 HIGH, and NIST has not yet provided an assessment.","solution":"To remediate this issue, users should upgrade to version 2.0.24.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-18655","publishedAt":"2026-08-03T20:17:17.557Z","cveId":"CVE-2026-18655","cweIds":["CWE-923"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["prompt_injection"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Amazon MQ MCP Server","awslabs.amazon-mq-mcp-server","Amazon MQ for RabbitMQ"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Amazon MQ MCP Server RabbitMQ broker tools leak credentials via crafted endpoint","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"required","exploitMaturity":"unknown","epssScore":0.00423,"epssCheckedAt":"2026-11-04T12:08:33.950Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-02T06:10:37.615Z","patchAvailable":null,"disclosureDate":"2026-08-03T20:17:17.557Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":["AML.T0051"],"fixes":[]}}
