Sven is the core package management software underlying Seven OS. We take vulnerabilities critically, especially those involving signature verification, dependency resolution parsing, or the snapshot/rollback algorithms.

Only the latest release (currently v1.x.x) actively receives security patches. Users are strongly encouraged to utilize the sven self-update mechanism regularly or stay current with the Seven OS automated updater.

If you discover a vulnerability in Sven (for example, a method to bypass the Double-Check integrity engine or poison the LocalDB), do not report it publicly via a GitHub Issue.

Instead, please email the vulnerability details directly to: harold@hanstech.com (Placeholder for official security contact)

You should expect an initial acknowledgement within 48 hours, and a full vulnerability assessment and potential patch timeline within 7 days.

Before reporting, please verify if your issue is handled by Sven's built-in defenses:

• Checksum Engine: All files are checked natively against /usr/bin/sha256sum prior to caching.
• Corrupted Chunk Detection: If a mirror drops bytes, the file size validator will trip, permanently banning the mirror for the session, failing over to a new mirror automatically, and wiping the rogue file.
• Traceback Shield: If a deliberate exploit crashes the Python runtime, Sven shields the stack trace, prevents the bad transaction, creates a safe rollback, and writes to error.log.
