Guzzle: Noncanonical host can bypass host-based checks

Impact In affected versions, Guzzle gives a transport the request URI as text and supplies the Host header separately. The cURL handlers set CURLOPTURL to the URI exactly as written and push that Host into CURLOPTHTTPHEADER; StreamHandler does the same through fopen. libcurl then parses the...

Server-Side Request Forgery (SSRF)

datamodel-code-generator is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to http.getbody in src/datamodelcodegenerator/http.py accepting --url targets and redirect chain targets without proper host/IP validation, which allows an attacker to perform server-side request...

GHSA-VX7X-VCC2-C44G datamodel-code-generator vulnerable to SSRF protection bypass via DNS rebinding

Summary datamodel-code-generator's anti-SSRF guard validates the resolved IP of a fetch target once and then lets httpx perform its own independent DNS resolution to connect, so the validated address is never pinned. A hostname that resolves to a public IP at validation time and a private IP at...
