Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Cryptographic signature bypasses and instruction index validation flaws in on-chain Solana programs permitted potential unauthorized reward distributions. These are mitigated by validating instruction offsets and using modern instruction loaders.
Auth Bypass: Authentication controls on critical pathways (such as multi-factor authentication, transaction relay endpoints, and email lookup logic) were prone to bypasses stemming from case-sensitivity anomalies and missing validation hooks.
Denial of Service: Misconfigured express rate-limiters, faulty IP extraction routines from headers behind multi-layered proxies, and unsafe parameter conversions (like parseInt causing NaN collisions) led to rate-limiting bypasses and backend resource exhaustion.
