baowzh hfly CVE-2025-14521

No vendor-released patch with a specific version number is available due to the rolling release model and vendor non-response to disclosure. Immediate remediation requires upgrading to the latest development build from the official baowzh hfly repository (post-commit 638ff9abe9078bc977c132b37acbe1900b63491c), verifying that the download handler validates filename parameters against a whitelist of allowed files or sanitizes path traversal sequences (e.g., rejecting ../, absolute paths, or null bytes). As a compensating control pending upstream fix, restrict /admin/index.php/datafile/download endpoint access to trusted internal networks via firewall or reverse proxy rules, and implement strict file access logging to detect exploitation attempts. Additionally, rotate any administrative credentials if they are default or widely known, as exploitation requires PR:L (low privileges) and may leverage weak admin accounts. Organizations should monitor the project's repository for updates and test them in staging environments before production deployment, given the vendor's apparent lack of formal security response processes.
