What is Solana weakness?

Could you please elaborate on the weaknesses of Solana? I've heard about its scalability and speed, but I'm curious to know if there are any significant downsides to this blockchain platform. Are there any known security vulnerabilities or scalability issues that could potentially affect its stability? Additionally, how does Solana compare to other leading cryptocurrencies in terms of decentralization and governance? It would be great to get a deeper understanding of its weaknesses to make a more informed decision about investing in it.
