QID 980300

QID 980300: Java (maven) Security Update for org.springframework:spring-webflux (GHSA-7pm4-g2qj-j85x)

Spring Framework, versions 5.2.x prior to 5.2.3 are vulnerable to CSRF attacks through CORS preflight requests that target Spring MVC (spring-webmvc module) or Spring WebFlux (spring-webflux module) endpoints. Only non-authenticated endpoints are vulnerable because preflight requests should not include credentials and therefore requests should fail authentication. However a notable exception to this are Chrome based browsers when using client certificates for authentication since Chrome sends TLS client certificates in CORS preflight requests in violation of spec requirements. No HTTP body can be sent or received as a result of this attack.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

  • CVSS V3 rated as Medium - 5.3 severity.
