CVE-2026-53539 is a denial of service vulnerability in Python-Multipart, a streaming multipart parser for Python. Prior to version 0.0.30, the parser is vulnerable to a denial of service attack when parsing application/x-www-form-urlencoded bodies. An attacker can submit a small crafted body and cause the parser to spend seconds of CPU per request, potentially exhausting worker processes. The vulnerabilit [truncated]
CVE-2026-48817 is a medium-severity vulnerability in Starlette, a lightweight ASGI framework. The issue allows attackers to invoke internal helper methods not intended as HTTP handlers due to unrestricted HTTP method handling. This occurs when an HTTPEndpoint subclass is registered without explicitly setting the 'methods' parameter, enabling non-standard HTTP methods to reach the endpoint. Affected applic [truncated]
CVE-2026-48818 is a high-severity Server-Side Request Forgery (SSRF) vulnerability in the StaticFiles feature of Starlette, a lightweight ASGI framework/toolkit, on Windows systems.
