CVE-2008-3773

Status: ModifiedMedium (4.3)—💥 Exploit

Cross-site scripting (XSS) vulnerability in vBulletin 3.7.2 PL1 and 3.6.10 PL3, when "Show New Private Message Notification Pop-Up" is enabled, allows remote authenticated users to inject arbitrary web script or HTML via a private message subject (aka newpm[title]).

CVSS

Exploitation probability (EPSS)

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.
