Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
SSRF: The scanner resolves external addresses and handles HTTP validation. Multiple bypasses involved improper handling of IPv4-mapped IPv6, local host loops, and late-stage DNS resolution after preflight checks. Developers must use comprehensive IP validation that acts on post-resolved addresses.
Denial of Service: String truncation on invalid UTF-8 character boundaries consistently triggers Rust panics, causing immediate denial of service. Safe slicing and truncation must verify byte boundaries prior to operation.
Auth Bypass: Flaws in JWT signature verification allowed validation bypasses. The implementation failed to explicitly reject the 'none' algorithm and did not mandate the 'iss' claim by default.
