Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The largest risk class with over 100 fixes; recurring flaws in token validation, session handling, and per-monitor/per-event permission checks (canView/canEdit) allowed unauthorized data access and privilege escalation.
Memory Corruption: Dozens of fixes in image and monitor code for buffer overflows, out-of-bounds reads/writes, and use-after-free, often from incorrect linesize/stride handling or unsafe pointer arithmetic.
SQL Injection: Recurring SQL injection via unsanitized filter attributes, ORDER BY columns, and user-controlled IDs; fixes added allowlists, parameterized queries, and input validation.
