CVE-2026-48932

A flaw in the Node.js HTTP client can cause request desynchronization in Node.js-based forwarding proxies that rebuild outbound headers from visible IncomingMessage headers while piping the original body to a reused backend connection. The root cause is that Node.js may omit headers beyond maxHea...

urllib3: urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via ProxyManager.connectionfromurl.urlopen with assertsamehost=False, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitiv...

urllib's cross-origin redirects preserve credential-bearing request headers, leading to potential credential leakage

Summary urllib supports redirect-following through followRedirect, which is expected behavior for an HTTP client. The issue is that, when following a redirect to a different origin, urllib preserves the caller-supplied request headers verbatim, including credential-bearing headers such as...

CVE-2026-55553

urllib is an HTTP client for Node.js that supports authentication, redirects, timeouts, and other request features. Prior to 4.9.1 and 2.44.1, urllib follows redirects through followRedirect but reuses caller-supplied options across origins. In src/HttpClient.ts, requestInternal recursively calls...
