GHSA-gfwj-fwqj-fp3v Improper Privilege Management in Spring Framework

• Maven org.springframework:spring-web: >= 5.2.0, < 5.2.15 → fixed in 5.2.15 • Maven org.springframework:spring-web: >= 5.3.0, < 5.3.7 → fixed in 5.3.7

In Spring Framework, versions 5.2.x prior to 5.2.15 and versions 5.3.x prior to 5.3.7, a WebFlux application is vulnerable to a privilege escalation: by (re)creating the temporary storage directory, a locally authenticated malicious user can read or modify files that have been uploaded to the WebFlux application, or overwrite arbitrary files with multipart request data.
