Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Unsafe FFI interactions with macOS/iOS CoreFoundation APIs previously led to a potential use-after-free vulnerability where underlying CFString references were dropped before the data was safely cloned into an owned Rust String. Developers must ensure strict lifecycle management and immediate ownership cloning when converting raw pointers using std::ffi::CStr::from_ptr.
Privilege Escalation: Overly permissive GitHub Actions configurations allowed local GITHUB_TOKEN credential persistence during repository checkout. Future workflow updates must maintain minimal permissions (permissions: read-all or {} paired with persist-credentials: false) to prevent token leakage in untrusted build steps.
