CVE-2026-22738: Unauthenticated RCE via SpEL Injection in Spring AI SimpleVectorStore

Server-Side Request Forgery in Spring AI Bedrock Converse module enables unauthenticated remote attackers to force the application server to issue HTTP requests to arbitrary internal or external destinations by supplying malicious media URLs in multimodal messages. Spring AI versions 1.0.0 through 1.0.4 and 1.1.0 through 1.1.3 are affected. The vulnerability carries a CVSS score of 8.6 with high confidentiality impact and changed scope, indicating potential access to internal network resources. No public exploit identified at time of analysis.

Spring AI Redis vector store implementations expose sensitive data through unescaped TAG field filter injection in versions 1.0.0-1.0.4 and 1.1.0-1.1.3. Unauthenticated remote attackers can craft malicious filter expressions that bypass query boundaries in RediSearch TAG blocks, allowing extraction of unauthorized information from the vector database (CVSS 7.5 High, C:H). No public exploit identified at time of analysis, though the vulnerability is straightforward to exploit given its low attack complexity (AC:L).

Cypher injection in Spring AI Neo4j vector store (versions 1.0.0 through 1.0.4 and 1.1.0 through 1.1.3) allows unauthenticated remote attackers to access confidential data stored in Neo4j databases. The vulnerability exists in Neo4jVectorFilterExpressionConverter where user-controlled filter expression keys are embedded into Cypher property accessors without proper backtick escaping, enabling attackers to break out of the intended property context and execute arbitrary Cypher queries. CVSS score of 7.5 reflects high confidentiality impact with network accessibility and low attack complexity, though no public exploit has been identified at time of analysis.
