CVE-2026-33405

Name of the Vulnerable Software and Affected Versions Pi-hole Admin Interface versions 6.0 through 6.4

Description The formatInfo() function in queries.js renders data.upstream, data.client.ip, and data.ede.text into HTML without proper escaping when a user expands a query row in the Query Log. This allows for stored HTML injection, although JavaScript execution is prevented by the server's Content Security Policy (CSP), which is a security layer that helps detect and mitigate certain types of attacks, including cross-site scripting and data injection.

Recommendations Update to version 6.5.
