CVE-2009-1839
Status: ModifiedMedium (5.4)—💥 Exploit
Mozilla Firefox 3 before 3.0.11 associates an incorrect principal with a file: URL loaded through the location bar, which allows user-assisted remote attackers to bypass intended access restrictions and read files via a crafted HTML document, aka a "file-URL-to-file-URL scripting" attack.
CVSS
- Version: 2.0
- Vector: AV:N/AC:H/Au:N/C:C/I:N/A:N
- Base score: 5.4
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 7.12%
- Percentile among all scored CVEs: 94
- Score date: 10/14/2026
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.
