Technical ContextAI · show details
This vulnerability is classified as Cross-Site Scripting (XSS) (CWE-79), which allows attackers to inject malicious scripts into web pages viewed by other users. Grav is a flat-file content management system. In versions 1.7.42 and prior, the "/forgot_password" page has a self-reflected cross-site scripting vulnerability that can be exploited by injecting a script into the "email" parameter of the request. While this vulnerability can potentially allow an attacker to execute arbitrary code on the user's browser, the impact is limited as it requires user interaction to trigger the vulnerability. As of time of publication, a patch is not available. Server-side validation should be implemented to prevent this vulnerability. Affected products include: Getgrav Grav.

Priority Score
Attack Technique
Cross-Site Scripting occurs when an application accepts untrusted data and sends it to a web browser without proper validation or encoding.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
