GuzzleHTTP/guzzle versions before 7.14.2 fail to properly isolate Proxy-Authorization headers from origin servers in cURL handlers, allowing proxy credentials to be captured in origin logs during redirects or SOCKS proxy scenarios. This affects guzzlehttp/guzzle prior to 7.14.2 and can occur when...

Sensitive Information Exposure

datamodel-code-generator is vulnerable to Sensitive Information Exposure. The vulnerability is due to the reuse of Authorization, Cookie, and Proxy-Authorization headers when following cross-origin redirects while fetching remote schemas, which allows an attacker controlling a redirect target to...

EUVD-2026-50070

datamodel-code-generator generates Python data models from schema definitions. Prior to 0.63.0, src/datamodelcodegenerator/http.py getbody reuses Authorization, Cookie, and Proxy-Authorization headers when following cross-origin redirects while fetching remote schemas, allowing credentials scoped...

PT-2026-65616

Name of the Vulnerable Software and Affected Versions datamodel-code-generator versions prior to 0.63.0 Description When fetching remote schemas, the software re-sends original request headers to redirect targets even if the redirect changes the origin host, port, or scheme. This occurs within th...

GHSA-94PJ-82F3-465W Guzzle: Proxy-Authorization headers can be sent to origin servers

Impact In affected versions, the built-in cURL handlers CurlHandler and CurlMultiHandler put every first-class request header in cURL's origin header list CURLOPTHTTPHEADER. These handlers are the default when the PHP cURL extension is available. They move Proxy-Authorization to the proxy-only li...

Insufficiently Protected Credentials

Overview Affected versions of this package are vulnerable to Insufficiently Protected Credentials in the handling of Proxy-Authorization headers by the cURL handlers and stream handler. An attacker can obtain proxy credentials by controlling the origin server and capturing the credentials sent...

axios: Axios: Information disclosure of proxy credentials via redirect flows

A flaw was found in Axios. During specific proxy-to-direct redirect flows in the Node.js HTTP adapter, a remote attacker could exploit this vulnerability. The Proxy-Authorization header, which contains proxy credentials and is intended only for the outbound proxy, may be forwarded to the final...

axios: Axios: Information disclosure of proxy credentials via HTTP redirects

A flaw was found in Axios, a promise-based HTTP client, specifically in its Node.js HTTP adapter. When Axios is configured to use an authenticated proxy and follows a redirect, it may inadvertently send the Proxy-Authorization header, containing proxy credentials, to the redirect target. This can...

CVE-2026-44979

CVE-2026-44979 affects the @hapi/wreck HTTP client. Before 18.1.1, when following a 3xx redirect to a different hostname, the Proxy-Authorization header was not stripped (unlike Authorization and Cookie), potentially exposing forward-proxy credentials to the redirect target. The issue is fixed in...
