The email is persisted without sanitization and later rendered in the administrative FAQ editor template using Twig\u2019s |raw filter, which bypasses the framework\u2019s auto\u2011escaping. When an administrator opens the editor, the e\u2011mail address is injected into the page\u2019s HTML, allowing arbitrary JavaScript to execute in the context of any admin user who views the page. This can lead to session hijacking, theft of administrative credentials, or defacement of the internal interface.", "risk_and_exploitability": "The CVSS base score of 5.4 indicates moderate severity, while the EPSS score of less than 1\u202f% suggests a low probability of exploitation in the wild.
