{"id":"CVE-2026-22745","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-22745","summary":"Spring MVC and WebFlux applications are vulnerable to Denial of Service attacks when resolving static resources","details":"Spring MVC and WebFlux applications are vulnerable to Denial of Service attacks when resolving static resources.\n\n\nMore precisely, an application can be vulnerable when all the following are true:\n\n  *  the application is using Spring MVC or Spring WebFlux\n  *  the application is serving static resources from the file system\n  *  the application is running on a Windows platform\n\n\nWhen all the conditions above are met, the attacker can send malicious requests that are slow to resolve and that can keep HTTP connections in use. This can cause a Denial of Service on the application.","published":"2026-04-29T12:33:07Z","modified":"2026-09-10T03:50:43.783544605Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":{"score":0.00341,"percentile":0.27495,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.springframework:spring-webflux","fixedVersion":"7.0.7"},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","fixedVersion":"6.2.18"},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","fixedVersion":null},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","fixedVersion":null},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","fixedVersion":"7.0.7"},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","fixedVersion":"6.2.18"},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","fixedVersion":null},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22745"},{"type":"PACKAGE","url":"https://github.com/spring-projects/spring-framework"},{"type":"WEB","url":"https://spring.io/security/cve-2026-22745"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:43.783544605Z"}}
