Summary

Event Viewer (eventvwr.exe) in Microsoft Windows does not properly display log data that contains '%' (percent) characters, which might make it impossible to use Event Viewer to determine the actual data that triggered an event, and might produce long strings that are not properly handled by certain processes that rely on Event Viewer.

Exploit prediction

1.68% chance of exploitation in the next 30 days, higher than 77% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
