CVE-2006-3199

Status: ModifiedMedium (5)—💥 Exploit

Opera 9 allows remote attackers to cause a denial of service (crash) via an A tag with an href attribute with a URL containing a long hostname, which triggers an out-of-bounds operation.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Base score: 5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 15%
Percentile among all scored CVEs: 97
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.
