Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Expression (org.springframework:spring-expression) versions before 5.3.39 are vulnerable to a denial of service. An attacker who can supply a specially crafted Spring Expression Language (SpEL) expression to an application that evaluates user-supplied SpEL can cause a denial of service condition. Upgrade spring-expression to version 5.3.39 or later.
