CVE-2026-105290: feelec-yishu feelcrm-os server-side request forgery in getCurlData

CVE-2026-105290 · Severity: high · CVSS 7.3 · Published 2026-10-05

FeelCRM is an open-source customer relationship management system that companies use to track leads, clients, and deals. An unauthenticated attacker can manipulate a URL parameter to force the server to make HTTP requests to internal network services or systems not directly accessible from the internet, potentially accessing sensitive internal resources or triggering unwanted actions on those services.

Technologies: Feelec-Yishu Feelcrm-Os. Vendors: Feelec-Yishu.

How to fix

Restrict network-level egress from the application server to only required external destinations; disable or require authentication for the getCurlData endpoint until a fix is deployed.

Technical details

The getCurlData endpoint in GoogleController.class.php accepts an attacker-controlled url parameter via GET without authentication and passes it directly to PHP cURL without validation of the scheme, host, or destination. An unauthenticated remote attacker can send arbitrary HTTP requests from the application server to internal loopback, private-network, or reserved-IP destinations. The vulnerability is a blind SSRF—the endpoint does not return the target response body, but the attacker can confirm request execution through timing or out-of-band channels.
