CVE-2026-74871: Dart Temp File Write Before Chmodcve-2026-74871-dart-temp-file-write-before-chmod
Sensitive data is written to a file before restrictive permissions are applied via chmod. This introduces a race condition (TOCTOU) where the file is readable by other local users with default permissions before chmod executes. Secure the containing directory or pre-create the file with secure permissions before writing data.
