CVE-2023-45803
CVSS 3.1 Score 4.2 of 10 (medium)
Details
Summary
CVE-2023-45803 affects urllib3, a popular Python HTTP client library. This vulnerability arises from urllib3's failure to remove the request body when redirecting from POST to GET methods, despite HTTP specifications. While not explicitly stated in the redirect section, this behavior can be inferred from various sources and is observed in other major HTTP client implementations. This issue, requiring a compromised trusted service, has low exploitability due to the unlikelihood of sensitive data being sent in HTTP request bodies and the rare condition of service compromise. To mitigate the risk, users should update to versions 1.26.18 or 2.0.7, disable redirects for unexpected services, or handle redirects manually by stripping request bodies.
