CVE-2015-3440
Status: ModifiedMedium (4.3)—💥 Exploit
Cross-site scripting (XSS) vulnerability in wp-includes/wp-db.php in WordPress before 4.2.1 allows remote attackers to inject arbitrary web script or HTML via a long comment that is improperly stored because of limitations on the MySQL TEXT data type.
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: 17%
- Percentile among all scored CVEs: 97
- 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.
