Vulnerability from fkie_nvd - Published: 2026-09-23 16:16 - Updated: 2026-09-23 19:17
Severity
7.3 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Summary
IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to RAG poisoning via unauthenticated runbook upsert (CWE-74) in the FTM AI agent server (api.vectordb.runbooks.js:51). An unauthenticated attacker can insert malicious runbook content into the agent's vector database to steer AI-driven MCP tool calls, potentially triggering unauthorized payment actions or exfiltrating payment data.
