CVE 修复
CVE ID: CVE-2026-22702
漏洞描述: virtualenv 20.36.1 之前版本存在 TOCTOU (Time-of-Check-Time-of-Use) 竞争条件漏洞。在目录创建过程中，由于检查目录是否存在和创建目录之间存在时间窗口，本地攻击者可通过符号链接攻击重定向 app_data 和锁目录的文件操作。
修复方案: 使用
os.makedirs(path, exist_ok=True)替代先检查再创建的模式，消除 TOCTOU 竞争条件。受影响版本: < 20.36.1
当前版本: 20.25.1+ds-1
验证状态: ✅ 已通过 quilt 验证
