CVE-2010-1939

Status: ModifiedHigh (7.6)—💥 Exploit

Use-after-free vulnerability in Apple Safari 4.0.5 on Windows allows remote attackers to execute arbitrary code by using window.open to create a popup window for a crafted HTML document, and then calling the parent window's close method, which triggers improper handling of a deleted window object.

CVSS

Version: 2.0
Vector: AV:N/AC:H/Au:N/C:C/I:C/A:C
Base score: 7.6

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 15%
Percentile among all scored CVEs: 97
Score date: 10/9/2026

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.
