CVE-2026-18875

Description

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.
