🛡️ Sentinel: [MEDIUM] Fix insecure file permissions for saved output#6
Conversation
🚨 Severity: MEDIUM 💡 Vulnerability: The `maybe_write_text` utility used `std::fs::write` which saves output files (like PSBTs and Offers) with insecure default permissions, making them readable by other users. 🎯 Impact: Local privilege escalation/exposure of sensitive transaction data. 🔧 Fix: Replaced `std::fs::write` with `crate::paths::write_secure_file` to enforce `0o600` permissions. ✅ Verification: Ran `cargo test` and `cargo check`. Added Sentinel journal entry. Co-authored-by: bitcoiner-dev <75873427+bitcoiner-dev@users.noreply.github.com>
