Deeper analysisAI

CVE-2026-22743 is a Cypher injection vulnerability in the Neo4jVectorFilterExpressionConverter of Spring AI's spring-ai-neo4j-store module. The vulnerability arises when a user-controlled string is passed as a filter expression key; the doKey() method embeds this key into a backtick-delimited Cypher property accessor in the form node.`metadata.<key>`, stripping only double quotes without escaping embedded backticks. This flaw affects Spring AI versions from 1.0.0 before 1.0.5 and from 1.1.0 before 1.1.4.

An unauthenticated remote attacker can exploit this vulnerability over the network with low attack complexity and no user interaction required, as reflected in its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). By supplying a malicious filter expression key containing crafted backticks, the attacker can inject arbitrary Cypher queries, resulting in high-impact confidentiality loss through unauthorized access to sensitive data in the Neo4j database.

The official Spring security advisory at https://spring.io/security/cve-2026-22743 details mitigation steps, recommending upgrades to patched versions: Spring AI 1.0.5 or later for the 1.0.x series, and 1.1.4 or later for the 1.1.x series. This issue is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
