Summary
An issue was discovered in zzzphp cms 1.5.8. del_file in /admin/save.php allows remote attackers to delete arbitrary files via a mixed-case extension and an extra '.' character, because (for example) "php" is blocked but path=F:/1.phP. succeeds.
Exploit prediction
1.39% chance of exploitation in the next 30 days, higher than 72% of all scored CVEs (FIRST EPSS, 2026-11-09).
