CVE-2006-4157

Status: ModifiedMedium (6.8)—💥 Exploit

Cross-site scripting (XSS) vulnerability in index.php in Yet another Bulletin Board (YaBB) allows remote attackers to inject arbitrary web script or HTML via the categories parameter.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
Base score: 6.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 1.95%
Percentile among all scored CVEs: 80
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.
