A Spring RSocket application is exposed to a memory leak via a malformed SETUP frame. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.0.RELEASE - 5.2.25.RELEASE

Applications that evaluate user-supplied Spring Expression Language (SpEL) expressions may be vulnerable to a Denial of Service (DoS) attack when the power operator (^) is used with a BigDecimal or BigInteger operand and a large exponent value. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

Spring Framework applications that use Spring's data binding infrastructure to apply user-supplied property paths onto a target object may be vulnerable to a Denial of Service (DoS) attack. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

A Spring WebFlux application that supports WebSocket connections may expose indirectly sensitive user information by including request headers in an exception reason. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier

Applications that use UriComponentsBuilder in Spring Framework to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a open redirect https://cwe.mitre.org/data/definitions/601.html  attack or to a SSRF attack if the URL is used after passing validation checks.

This is the same as CVE-2024-22243 https://spring.io/security/cve-2024-22243 , but with different input.

A flaw was found in Spring Framework. Certain versions of Spring Framework's Expression Language were not restricting the size of Spring Expressions. This could allow an attacker to craft a malicious Spring Expression to cause a denial of service on the server.

In Spring Framework versions 6.0.0 - 6.0.13, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

Specifically, an application is vulnerable when all of the following are true:

the application uses Spring MVC or Spring WebFlux io.micrometer:micrometer-core is on the classpath an ObservationRegistry is configured in the application to record observations

Typically, Spring Boot applications need the org.springframework.boot:spring-boot-actuator dependency to meet all conditions.
