The National Vulnerability Database provides the following description for this vulnerability: Applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn are vulnerable to path traversal attacks. An attacker can craft malicious HTTP requests and obtain any file on the file system that is also accessible to the process in which the Spring application is running.

Note: To mitigate CVE-2024-38819, we upgraded to a fixed version of Spring in our latest security and bug fix releases, which are noted as fixed releases above. Moving to one of the fixed versions will stop security scanners from detecting this CVE in those releases.
We also want to share that Confluence doesn't utilize the Spring framework in a way that makes any versions vulnerable to this CVE.  More specifically we don't utilize the vulnerable packages "org.springframework.web.reactive.function.server" or "org.springframework.web.servlet.function" in any version of Confluence.  Versions not listed as fixed are not vulnerable to this CVE but may receive alerts from scanners.
