Summary
Bloxx Web Filtering before 5.0.14 does not properly interpret X-Forwarded-For headers during access-control and logging operations for HTTPS connection attempts, which allows remote attackers to bypass intended IP address and domain restrictions, and trigger misleading log entries, via a crafted header.
Exploit prediction
2.05% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-09).
