Because the attribute is stored without proper sanitization or escaping, the injected script runs in the browser of any user who views the affected page, enabling malicious actions such as cookie theft, session hijacking, or further cross\u2011site attacks. The weakness is a classic stored cross\u2011site scripting flaw (CWE\u201179).", "risk_and_exploitability": "The vulnerability scores a CVSS base score of 6.4, indicating a moderate severity. The EPSS score is less than 1%, suggesting that exploitation is unlikely in the near term. It is not listed in the CISA KEV catalog.
