CVE-2026-40966: VMware Spring Ai

Medium severity, CVSS 5.9. EPSS: 0.4% chance of exploitation in the next 30 days.

In Spring AI, an attacker can bypass conversation isolation and exfiltrate sensitive memory from other users’ chat histories, including secrets and credentials, by injecting filter logic through conversationId. Only applications that use VectorStoreChatMemoryAdvisor and pass user-supplied input as a conversationId are affected.

Affected products

• VMware Spring Ai: from 1.0.0, before 1.0.6 (fixed in 1.0.6); from 1.1.0, before 1.1.5 (fixed in 1.1.5)
