| Doc Text: |
A flaw was found in guzzlehttp/guzzle, where it fails to properly isolate Proxy-Authorization headers from origin servers when using cURL handlers. A remote attacker could exploit this vulnerability when requests are redirected, bypassed, or sent through SOCKS proxies that Guzzle misclassifies as direct connections. This improper isolation allows attackers to capture sensitive proxy credentials through origin server access logs, leading to information disclosure.
