Status: ModifiedHigh (7.5)—
Microsoft Excel 97, 2000, and 2002 allows remote attackers to execute arbitrary code via a spreadsheet with a malicious XLM (Excel 4) macro that bypasses the macro security model.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
- Base score: 7.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 19%
- Percentile among all scored CVEs: 97
- Score date: 10/10/2026
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).
