The server directly echoes the value of the $_GET['sccd'] parameter into an HTML alert <div> without sanitization or encoding. An attacker can supply arbitrary JavaScript or HTML tags in that parameter, causing the payload to execute in the victim\u2019s browser when the page is displayed. This enables client\u2011side code execution that can steal session cookies, deface the interface, or redirect users to malicious sites. Because the malicious script runs in the context of the victim\u2019s session, it has the potential to exfiltrate sensitive information and hijack sessions, affecting confidentiality and integrity of user data. The impact is limited to the individual victim\u2019s browser session, but it can be exploited against any user who visits the crafted URL.", "risk_and_exploitability": "CVSS score of 9.3 denotes a high severity vulnerability. The EPSS score is not provided, so exact exploit probability cannot be quantified, but the lack of an authentication requirement and the visibility of the vulnerable endpoint make exploitation straightforward. The vulnerability is not listed in CISA\u2019s KEV catalog, suggesting no public reports of active exploitation at the time of analysis. The likely attack vector is a reflected XSS attack executed via a crafted URL (web). An attacker simply needs to lure or trick a user into visiting a URL containing a malicious sccd value; no user credentials or privileged access are required. Given the high CVSS score, the risk is considered high for any organization running a vulnerable WeGIA instance."}}}}, "created": "2026-03-20T14:13:38.859587+00:00", "updated": "2026-03-20T14:13:38.859623+00:00", "vendors": []}
