No description provided.

To fix the problem, sanitize the user-provided guid before including it in any log entries. For plain-text logs, this typically means removing line breaks and other control characters that could be interpreted as log delimiters, and optionally trimming whitespace. We should also avoid altering the behavior of the application itself, so the original guid value must still be used for the database query and exceptions; only the logged representation should be sanitized.

The best minimal fix here is to introduce a local sanitized variable inside GetFosterFamily, derived from guid by removing \r and \n (and optionally trimming). Then use this sanitized variable in the _logger.LogError call while leaving all other logic untouched. We do not need new imports; string.Replace and string.Trim are part of the BCL. Concretely, inside GetFosterFamily(string guid), right before the try (or at the top of the method), define var safeGuid = guid?.Replace("\r", "").Replace("\n", "").Trim(); and change the logging call on line 84 to use safeGuid instead of guid. No other files strictly need changes; the controller already sanitizes guid in its own logging statement using Replace(Environment.NewLine, "").
