Overview

CVE-2025-34087 is a high-severity vulnerability. It was published on July 3, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

An authenticated command injection vulnerability exists in Pi-hole versions up to 3.3. When adding a domain to the allowlist via the web interface, the domain parameter is not properly sanitized, allowing an attacker to append OS commands to the domain string. These commands are executed on the underlying operating system with the privileges of the Pi-hole service user.

This behavior was present in the legacy AdminLTE interface and has since been patched in later versions.

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.
