The vulnerability resides within the ws Endpoint component and is triggered by manipulating the \u003ccode\u003esource_urls\u003c/code\u003e argument. This flaw allows a remote attacker to potentially force the application to make requests to arbitrary internal or external resources. A publicly disclosed exploit exists, increasing the risk of exploitation. The developers were notified through an issue report, but have not yet responded. This vulnerability is a significant concern for organizations using gpt-researcher, as it can lead to sensitive data exposure or further attacks originating from the application\u0026rsquo;s server.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a gpt-researcher instance running version 3.4.3 or earlier.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious request containing a manipulated \u003ccode\u003esource_urls\u003c/code\u003e argument.
