{"cve":"CVE-2020-5397","nvd":{"published":"2020-01-17T19:15:14.727","modified":"2026-06-17T03:21:24.700","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-352"],"references":["https://pivotal.io/security/cve-2020-5397","https://www.oracle.com//security-alerts/cpujul2021.html","https://www.oracle.com/security-alerts/cpuapr2020.html","https://www.oracle.com/security-alerts/cpujul2020.html","https://www.oracle.com/security-alerts/cpujul2022.html"],"products":["oracle:application_testing_suite","oracle:communications_brm_-_elastic_charging_engine","oracle:communications_diameter_signaling_router","oracle:communications_element_manager","oracle:communications_policy_management","oracle:communications_session_route_manager","oracle:enterprise_manager_base_platform","oracle:financial_services_regulatory_reporting_with_agilereporter","oracle:flexcube_private_banking","oracle:healthcare_master_person_index","oracle:insurance_calculation_engine","oracle:insurance_policy_administration_j2ee","oracle:insurance_rules_palette","oracle:mysql_enterprise_monitor","oracle:rapid_planning","oracle:retail_assortment_planning","oracle:retail_back_office","oracle:retail_central_office","oracle:retail_financial_integration","oracle:retail_integration_bus","oracle:retail_order_broker","oracle:retail_point-of-service","oracle:retail_predictive_application_server","oracle:retail_returns_management","oracle:retail_service_backbone","oracle:weblogic_server","vmware:spring_framework"],"source":"nvd","synced_at":"2026-10-19T21:01:01.339895972+00:00"},"epss":{"cve":"CVE-2020-5397","score":0.02551,"percentile":0.85041,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7pm4-g2qj-j85x","url":"https://osv.dev/vulnerability/GHSA-7pm4-g2qj-j85x","summary":"CSRF attack via CORS preflight requests with Spring MVC or Spring WebFlux","modified":"2024-03-15T16:12:40.150978Z","packages":[{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","purl":"pkg:maven/org.springframework/spring-webmvc","ranges":[">=5.2.0 <5.2.3"],"fixed":["5.2.3"]},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","purl":"pkg:maven/org.springframework/spring-webflux","ranges":[">=5.2.0 <5.2.3"],"fixed":["5.2.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
