Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: URL-encoded body parsing is highly vulnerable to resource exhaustion through oversized payloads, excessive parameter splitting, or deep object nesting, as evidenced by CVE-2024-45590. Attackers can exploit unbounded parsing behavior to cause high CPU usage or memory starvation.
Denial of Service: Bypassing limit options via invalid input types (like non-numeric strings, Booleans, or NaN) can result in silent failures where limits parse to null, effectively disabling payload size restrictions and leaving the system vulnerable to memory exhaustion.
