Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Symlink Attack / Arbitrary File Write: Privileged processes writing log files can be tricked into following a symlink to overwrite arbitrary files; fixed with O_EXCL but any new file-creation path must enforce the same.
Path Traversal: Usernames containing backslashes can escape the log directory on Windows; sanitization is required for all filename components derived from untrusted input.
