🛡️ Sentinel: [CRITICAL] Fix JPQL injection in ChannelScheduleController

[ManupaKDU]

🚨 Severity: CRITICAL
💡 Vulnerability: JPQL Injection. In ChannelScheduleController.completeSession(), user-provided input was concatenated directly into a LIKE clause: like '%" + query.toUpperCase() + "%'. This bypassed the ORM's sanitization, allowing potential injection of malicious JPQL syntax.
🎯 Impact: An attacker could craft specific autocomplete queries to manipulate the database query logic, potentially reading unauthorized data (such as other doctors' schedules or user information) or causing denial-of-service through complex queries.
🔧 Fix: Refactored the JPQL string to use named parameters (:query and :staffId) and utilized the JPA facade's parameterized findByJpql(sql, params) method. The case-insensitive search logic was moved safely into the query string via the upper() function.
✅ Verification:

1. Confirmed parameterized implementation (cat -n src/main/java/com/divudi/bean/channel/ChannelScheduleController.java | sed -n '680,700p').
2. Run tests to ensure no regressions using ./detect-maven.sh test.
