CVE-2009-1620

Status: ModifiedMedium (4.3)—💥 Exploit

Multiple cross-site scripting (XSS) vulnerabilities in input.php in MataChat allow remote attackers to inject arbitrary web script or HTML via the (1) nickname and (2) color parameters.

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: 1.19%
Percentile among all scored CVEs: 67
Score date: 10/8/2026

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.
