Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-30711 is a Cross-Site Request Forgery (CSRF) vulnerability found in GRR, an open-source booking management system by Devome. It affects version 4.4.2 and was fixed in version 4.5.0. The vulnerability arises because the application lacks CSRF protection and uses GET requests for operations that change the system state.'}, {'type': 'paragraph', 'content': "This design flaw allows an attacker to create malicious web pages that, when visited by an authenticated administrator, automatically send unauthorized GET requests to the GRR server. These requests can alter critical configurations without the administrator's knowledge or consent."}, {'type': 'paragraph', 'content': 'For example, an attacker can silently change backup settings or set specific passwords by exploiting this vulnerability. Since administrators can deploy external PHP modules, compromising an admin account through this CSRF flaw could potentially lead to remote code execution on the server.'}] [1]
How can this vulnerability impact me? :
[{'type': 'paragraph', 'content': "This vulnerability can have significant impacts including unauthorized changes to critical system configurations by attackers without the administrator's consent."}, {'type': 'paragraph', 'content': 'If an attacker successfully exploits this vulnerability, they can modify backup settings, change passwords, and potentially execute remote code on the server by leveraging the ability of administrators to deploy external PHP modules.'}, {'type': 'paragraph', 'content': 'Such unauthorized administrative actions can compromise the integrity, availability, and security of the system, leading to potential data breaches, service disruptions, or further exploitation.'}] [1]
