Cause (Documented platform behavior): urllib3 emits InsecureRequestWarning on each unverified HTTPS request made from a connection pool.
Fix status: documented_behavior
Misleading approaches:
- Suppressing the warning with urllib3.disable_warnings() while leaving verification off.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://files.pythonhosted.org/packages/92/9d/c4e665119135114480843e7ab388fa94d8480650450e6f8e26b70d323a4c/urllib3-2.8.0-py3-none-any.whl#urllib3/connectionpool.py (github_source, unknown, documented_behavior): _validate_conn warns InsecureRequestWarning 'Unverified HTTPS request is being made to host ...' when the connection is not verified.

Problem details
- Observed symptom
- Repeated warnings for every request after verification was disabled; credentials and API keys now travel over connections that could be intercepted.
- Context
- Product: urllib3 / requests Component: TLS verification warnings Operation: requests.get(..., verify=False) or urllib3 cert_reqs='CERT_NONE' added to get past CERTIFICATE_VERIFY_FAILED behind TLS-inspecting proxies Affected versions: unknown Environment: unknown Exception: urllib3.exceptions.InsecureRequestWarning Packages: urllib3 checked 2.8.0 Trigger: HTTPS request with certificate verification disabled.
- Environment
- Unknown · not established
- Symptom signature
- Literal error text
- Unverified HTTPS request is being made to host '{conn.host}'. Adding certificate verification is strongly advised.

Proposed fix: [urllib3 / requests verify=False] 'InsecureRequestWarning: Unverified HTTPS request is being made to host ...' — agents 'fix' TLS errors by disabling verification; the real fix is supply
Recommended action: Revert verify=False; point REQUESTS_CA_BUNDLE / verify= to the corporate or proxy CA bundle (or use truststore for the OS store); never ship code that suppresses this warning to hide disabled verification.
