LFI / Path Traversal

Read local files, then escalate. PHP wrappers turn LFI into source disclosure or RCE (log poisoning, php://filter chains). Later entries defeat filters via encoding and traversal padding.

Read local files, then escalate. PHP wrappers turn LFI into source disclosure or RCE (log poisoning, php://filter chains). Later entries defeat filters via encoding and traversal padding.

Do not copy blind

Identify the parser, sink, encoding, and expected non-vulnerable behavior before choosing a sample. Prefer non-destructive markers.
