CVE-2004-1563

Status: ModifiedMedium (4.3)—💥 Exploit

Multiple cross-site scripting (XSS) vulnerabilities in w-Agora 4.1.6a allow remote attackers to execute arbitrary web script or HTML via the (1) thread parameter to download_thread.php, (2) loginuser parameter to login.php, or (3) userid parameter to forgot_password.php.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
Base score: 4.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.01%
Percentile among all scored CVEs: 80
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
