Potential fix for https://github.com/tlcsdm/eclipse-rcp-example/security/code-scanning/6
To fix Zip Slip safely, normalize and validate each computed output path before any file operation. The best approach here is:
target.toAbsolutePath().normalize()).resolvedPath = targetPath.resolve(entry.getName()).normalize()if (!resolvedPath.startsWith(targetPath)) throw new IOException(...)resolvedPathfor directory creation and file copy.This single validation point addresses all three alert variants (directory creation, parent directory creation, and file copy).
