The tweet mentions a technique to prevent CSPT by URL-encoding slashes in the input. It also hints at the possibility of bypassing server-side parsers, especially in the context of a WAF bypass. This could be significant in scenarios where the WAF may not properly handle or detect encoded slashes, leading to potential bypasses. It's crucial for security teams to address such evasion techniques and ensure WAF configurations are robust against them.
