This can cause a denial of service by breaking the front-end application for clients.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","score":3.1},"cwes":["CWE-524"],"references":["https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L&version=3.1","https://spring.io/security/cve-2026-22741"],"products":["vmware:spring_framework"],"source":"nvd","synced_at":"2026-10-26T20:34:58.897451322+00:00"},"epss":{"cve":"CVE-2026-22741","score":0.00236,"percentile":0.14434,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-wg35-8jpf-2xv3","url":"https://osv.dev/vulnerability/GHSA-wg35-8jpf-2xv3","summary":"Spring MVC and WebFlux applications are vulnerable to cache poisoning when resolving static resources.","modified":"2026-09-10T03:51:04.065980932Z","packages":[{"ecosystem":"Maven","name":"org.springframework:spring-webflux","purl":"pkg:maven/org.springframework/spring-webflux","ranges":[">=7.0.0 <7.0.7"],"fixed":["7.0.7"]},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","purl":"pkg:maven/org.springframework/spring-webflux","ranges":[">=6.2.0 <6.2.18"],"fixed":["6.2.18"]},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","purl":"pkg:maven/org.springframework/spring-webflux","ranges":[">=6.1.0 <=6.1.26"],"fixed":[]},{"ecosystem":"Maven","name":"org.springframework:spring-webflux","purl":"pkg:maven/org.springframework/spring-webflux","ranges":["<=5.3.47"],"fixed":[]},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","purl":"pkg:maven/org.springframework/spring-webmvc","ranges":[">=7.0.0 <7.0.7"],"fixed":["7.0.7"]},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","purl":"pkg:maven/org.springframework/spring-webmvc","ranges":[">=6.2.0 <6.2.18"],"fixed":["6.2.18"]},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","purl":"pkg:maven/org.springframework/spring-webmvc","ranges":[">=6.1.0 <=6.1.26"],"fixed":[]},{"ecosystem":"Maven","name":"org.springframework:spring-webmvc","purl":"pkg:maven/org.springframework/spring-webmvc","ranges":["<=5.3.47"],"fixed":[]}]}],"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).
