Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
SSRF: Absolute URLs with a host different from base_uri could be requested, allowing SSRF to internal services; fix added a host allowlist check but only for the initial request path.
Improper Certificate Validation: SSL verification was disabled by default (VERIFY_NONE), enabling MITM; fix defaults to VERIFY_PEER with system store, but custom connection adapters may still override.
Open Redirect: Redirect handling sets self.path from response['location'] without validating the target host or scheme; two fixes only changed method/cookie handling, not target validation.
