CVE-2005-4809
Status: ModifiedMedium (5)—💥 Exploit
Mozilla Firefox 1.0.1 and possibly other versions, including Mozilla and Thunderbird, allows remote attackers to spoof the URL in the Status Bar via an A HREF tag that contains a TABLE tag that contains another A tag.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
- Base score: 5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 6.14%
- Percentile among all scored CVEs: 93
- Score date: 10/11/2026
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.
