Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Inadequate path validation during resolution allowed directory traversal, risking arbitrary local file disclosure if user-provided paths bypass configured root directory boundaries.
Signature Bypass: Truncation of cryptographic hashes to 8 characters made the signature validation susceptible to brute-force or collision attacks, undermining request integrity controls.
Auth Bypass: Using a generic UriSigner allowed parameter manipulation; swapping to a custom runtime filter signer was necessary to strictly restrict the parameters verified.
