• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

Due to a DOM-Based Cross-Site Scripting (XSS) vulnerability, an unauthenticated attacker could generate a malicious link and make it publicly accessible. If an authenticated user accesses this link, client-side code reads the attacker-controlled input and writes it into the DOM without proper sanitization, causing attacker-supplied script to execute in the victim�s browser context. This could allow the attacker to access or modify information within the victim�s browser scope, impacting confidentiality and integrity, while availability remains unaffected.
