Erlang/OTP -- httpc leaks authentication headers on cross-host redirect

https://github.com/erlang/otp/security/advisories/GHSA-m75x-4vwg-ggjh reports: The HTTP client httpc in inets now removes Authorization, Proxy-Authorization, Cookie, Referer, and Origin headers when following a redirect to a different host or port, following the requirements of RFC 9110 section...

Information Exposure

Axios is vulnerable to Information Exposure. The vulnerability is due to improper handling of the Proxy-Authorization header in the Node.js HTTP adapter, where proxy credentials can be retained across redirects and inadvertently sent to a redirected destination after the request is no longer rout...

Medium: perl-libwww-perl

Issue Overview: LWP::UserAgent versions before 6.83 for Perl leak Authorization and Proxy-Authorization headers on cross-origin redirects. On a 3xx response, the redirect handler strips only Host and Cookie before issuing the follow-up request. Caller-supplied Authorization and Proxy-Authorizatio...

CVE-2026-44503

The RedirectHandler middleware in microsoft/kiota-java com.microsoft.kiota:microsoft-kiota-http-okHttp v1.9.0 and other Kiota libraries fails to strip sensitive HTTP headers when following 3xx redirects to a different host or scheme. Only the Authorization header is removed; Cookie,...

Axios: Proxy-Authorization Credential Leak to Origin Server Across HTTP-to-HTTPS Redirect in Axios Node.js HTTP Adapter

Summary Axios’s Node.js HTTP adapter may forward a Proxy-Authorization header to a redirected origin during specific proxy-to-direct redirect flows. This affects Node.js usage, where an initial HTTP request is sent through an authenticated HTTP proxy, redirects are followed, and the redirected UR...

Insertion of Sensitive Information Into Sent Data

Overview org.webjars.npm:axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data in the setProxy function. An attacker can obtain sensitive proxy credentials by controlling a redirect...

GHSA-J5F8-GRM9-P9FC Axios: Proxy-Authorization header leaks to redirect target when proxy is re-evaluated to direct connection

Summary Axios’ Node.js HTTP adapter can leak proxy credentials to a redirect target in affected versions. When a request is sent through an authenticated proxy, Axios may add a Proxy-Authorization header. If Axios then follows a redirect and the redirected request is no longer sent through that...

Name of the Vulnerable Software and Affected Versions Axios versions prior to 0.32.0 Axios versions prior to 1.16.0 Description The Node.js HTTP adapter in Axios may forward a Proxy-Authorization header to a redirected origin during specific proxy-to-direct redirect flows. This occurs when an...

GHSA-654M-C8P4-X5FP Axios has a Patch Bypass: Proxy-Authorization Header Injection via Prototype Pollution — Incomplete Null-Prototype Fix

Patch Bypass Proxy-Authorization Header Injection via Prototype Pollution — Incomplete Null-Prototype Fix in Axios 1.15.2 Summary The Object.createnull fix introduced in Axios 1.15.2 GHSA-q8qp-cvcw-x6jj protects the top-level config object from prototype pollution. However, nested objects created...

Prototype Pollution

Overview org.webjars.npm:axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to Prototype Pollution via the setProxy function. An attacker can inject arbitrary credentials into the Proxy-Authorization header of proxied HTTP requests b...

Name of the Vulnerable Software and Affected Versions Axios versions 1.15.2 through 1.15.9 Description Nested objects created by the merge function in utils.js are constructed as plain objects, meaning they retain Object.prototype in their prototype chain. The setProxy function in...

GHSA-VHJM-W67Q-G75C @hapi/wreck leaks sensitive `Proxy-Authorization` header across cross-hostname redirects

Impact When @hapi/wreck follows a 3xx redirect to a different hostname, only the Authorization and Cookie headers are stripped. The standard credential header Proxy-Authorization is forwarded intact to the redirect target, potentially exposing forward-proxy credentials to a host outside the...

Insufficiently Protected Credentials

Overview @hapi/wreck is a HTTP Client Utilities library. Affected versions of this package are vulnerable to Insufficiently Protected Credentials due to leaking the sensitive Proxy-Authorization header across cross-hostname redirects.

curl: libcurl: Information disclosure via incorrect Proxy-Authorization header reuse

A flaw was found in libcurl. When a user performs a transfer over an HTTP proxy using Digest authentication and then reuses the same handle for a second transfer with a different proxy host, libcurl incorrectly sends the Proxy-Authorization header intended for the first proxy to the second proxy...
