No EPSS score is available, so the likelihood of exploitation cannot be quantified from the provided data, but the lack of a KEV designation suggests that it has not yet been widely exploited.

If the application exposes an interface for filter expressions, an attacker could supply malicious input to alter the query logic."}}}}, "created": "2026-04-28T08:15:23.494091+00:00", "title": "Unescaped Filter Expressions Enable Query Injection in Spring AI", "updated": "2026-04-28T19:30:27.392576+00:00", "vendors": ["spring", "spring$PRODUCT$spring"]}
