CVE-2025-64059: CWE-79 Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') in getgrav Grav
CVE-2025-64059 is a low-severity vulnerability in Grav version 1.7.50.2 where administrators can inject JavaScript via the Home Page editor, leading to potential stored cross-site scripting (XSS). The significance of this vulnerability is debated because administrators already have permissions to modify templates, install plugins, and upload executable content, which may reduce the practical impact of this XSS risk.
AI Analysis
Technical Summary
Grav 1.7.50.2 contains an improper neutralization of input vulnerability (CWE-79) that allows administrators to enter JavaScript code through the Home Page editor. This could result in stored cross-site scripting. However, since administrators have broad capabilities including template modification and plugin installation, the practical risk of this XSS is considered limited or disputed.
Potential Impact
The vulnerability allows injection of JavaScript by users with administrative privileges, potentially enabling stored XSS. However, because administrators already have extensive control over the system, the incremental impact of this vulnerability is low. There is no indication of confidentiality or availability impact, and no known exploits in the wild.
Mitigation Recommendations
No official patch or remediation details are provided. Given the low severity and the administrative context of the vulnerability, standard administrative controls and limiting admin access are recommended. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
