"The newly discovered vulnerability, named GrafanaGhost, allows attackers to bypass client-side protections and security guardrails and link private data to external servers, exposing sensitive information in the background without user interaction."
"An attacker can exploit the weakness by targeting Grafana's AI-based capabilities when a user interacts with an entry log. In the background, a malicious prompt triggers the issue, turning Grafana into the exfiltration vessel."
"The data leaks the moment the system tries to display the image, as the AI companion makes a request to the attacker's server, sending the victim's data along as a URL parameter."
"The issue was that the attacker could fake the path of any company using Grafana by guessing the data structure and model, allowing for effective data exfiltration."
Grafana has a vulnerability named GrafanaGhost that enables attackers to bypass client-side protections and leak sensitive enterprise data. This open-source application, which processes various data sources, can be exploited when users interact with entry logs. Attackers can craft paths to external resources, prompting Grafana's AI to render images from malicious servers. This process sends sensitive data as URL parameters, exposing it without user interaction. The vulnerability allows attackers to manipulate Grafana's data structure to exfiltrate information effectively.
