Cross-conversation data exposure via unescaped metadata queries
Published Aug 27, 2026 · Updated Aug 27, 2026
Query injection in Spring AI 2.0.0 allows remote authenticated users to read chat messages across conversations via crafted metadata. RedisChatMemoryRepository.findByMetadata() interpolates unescaped caller values into RediSearch tag and text clauses, letting injected syntax exit a tag clause and match the entire index. Exploitation requires an application to pass user-controlled input for a tag-typed metadata field; it exposes indexed messages but does not modify them or interrupt service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
