What is CVE-2026-59319?
CVE-2026-59319 is a medium-severity code injection vulnerability in Spring AI, published on 27 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
RedisChatMemoryRepository.findByMetadata() builds RediSearch tag and text queries from caller-supplied metadata values without applying RediSearchUtil.escape(), unlike get(), clear(), and findByTimeRange() in the same class which do escape their inputs. An application that passes user-controlled values to findByMetadata() on a tag-typed metadata field allows an attacker to inject RediSearch syntax (e.g. x} | *) that breaks out of the tag clause and matches all indexed chat messages across every conversation in the index. Spring AI 2.0.0
