The vulnerability is located in the \u003ccode\u003e/settings/webhooks/create\u003c/code\u003e component. An attacker can exploit this flaw by crafting a malicious POST request that forces the server to make requests to internal resources. This can be leveraged to scan internal network infrastructure, potentially revealing sensitive information or accessing internal services that are not meant to be exposed to the outside world. The vulnerability was published on April 14, 2026. Exploitation requires the attacker to be able to send POST requests to the affected endpoint.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a Webkul Krayin CRM instance running version 2.2.x.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a POST request targeting the \u003ccode\u003e/settings/webhooks/create\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe POST request includes a malicious payload in the body, designed to trigger an SSRF vulnerability.
