The vulnerability stems from the insecure implementation of createTempDir() in IOUtil.java, which used File.createTempFile() followed by deletion and directory creation. This approach is vulnerable to TOCTOU attacks and insecure permissions. The commit diff shows this function was deprecated and replaced with Files.createTempDirectory(), which securely handles directory creation. The CVE description and patch notes explicitly identify this function as the root cause.
