CVE-2005-1476

Status: ModifiedMedium (5.1)—💥 Exploit

Firefox 1.0.3 allows remote attackers to execute arbitrary Javascript in other domains by using an IFRAME and causing the browser to navigate to a previous javascript: URL, which can lead to arbitrary code execution when combined with CVE-2005-1477.

CVSS

Version: 2.0
Vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
Base score: 5.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 17%
Percentile among all scored CVEs: 97
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.
