To fix the problem, sanitize the studentName parameter to remove (or otherwise escape) any newline or carriage return characters before logging it. This should be done immediately before the logging statement, only for the purpose of recording the log, so as not to affect the actual application logic or query.
The fix involves:
- Defining a local variable, e.g.,
safeStudentName, just before logging. - Assigning
safeStudentNamethe value ofstudentNamewith all newline-related characters removed (\r,\n, and optionally others). - Passing
safeStudentNameto the logger in place of the rawstudentName.
Only lines in the method containing the logged user data should be changed. No changes are needed elsewhere.

The best way to fix this problem is to sanitize the studentName variable before logging it. Specifically, remove any line break characters from the value, since log forging usually relies on inserting newlines. In general terms, update the logging line at line 99 (and optionally at line 93 for consistency) to log a sanitized version of studentName in place of the raw input.
Detailed steps:
- Before logging at line 99, create a sanitized version of
studentNameby removing (replacing) all occurrences of\rand\n. - Use the sanitized value in the logging statement.
- Do this for line 99.
- (Optional/recommended: do the same for line 93, which also logs user input.)
No new imports are required, as string.Replace is built in.
Only lines within the SearchCertificates method in api/CourseRegistration.API/Controllers/CertificatesController.cs are changed.
