Overview

CVE-2026-33432 is a critical-severity vulnerability. It was published on April 20, 2026 and has a CVSS 3.1 base score of 9.1 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions up to and including 8.2.8.2, when LDAP authentication is enabled, Roxy-WI constructs an LDAP search filter by directly concatenating the user-supplied login username into the filter string without escaping LDAP special characters. An unauthenticated attacker can inject LDAP filter metacharacters into the username field to manipulate the search query, cause the directory to return an unintended user entry, and bypass authentication entirely — gaining access to the application without knowing any valid password. As of time of publication, no known patches are available.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
