Title

OpenCTI 3.3.1 - Cross Site Scripting

Summary

OpenCTI 3.3.1 is vulnerable to a reflected cross-site scripting (XSS) attack via the /graphql endpoint. An attacker can inject arbitrary JavaScript code by sending a crafted GET request with a malicious payload in the query string, leading to execution of JavaScript in the victim's browser. For example, a request to /graphql?'"--></style></scRipt><scRipt>alert('Raif_Berkay')</scRipt> will trigger an alert. This vulnerability was discovered by Raif Berkay Dincel and confirmed on Linux Mint and Windows 10.

GHSA-F8VP-6QV4-W6C7

Vulnerability from github – Published: 2026-01-31 00:30 – Updated: 2026-01-31 00:30

Details

OpenCTI 3.3.1 is vulnerable to a reflected cross-site scripting (XSS) attack via the /graphql endpoint. An attacker can inject arbitrary JavaScript code by sending a crafted GET request with a malicious payload in the query string, leading to execution of JavaScript in the victim's browser. For example, a request to /graphql?'"-->alert('Raif_Berkay') will trigger an alert. This vulnerability was discovered by Raif Berkay Dincel and confirmed on Linux Mint and Windows 10.
