Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Struts 2 (package org.apache.struts:struts2-core, versions from 2.0.0 before 6.4.0) is vulnerable to flawed file upload logic. An attacker can manipulate file upload parameters to traverse paths and, under some circumstances, upload a malicious file that enables remote code execution. Upgrade to version 6.4.0 or later; applications not using the older FileUploadInterceptor-based upload logic are not affected.
