CVE-2026-66450Network attack vector

Unauthenticated file inclusion via template variable overwrite

Published Aug 13, 2026 · Updated Aug 13, 2026

Local file inclusion in Dylan Kuhn Geo Mashup 1.13.18 and earlier allows remote attackers to expose local server file contents. Search::load_template extracts query variables with EXTR_OVERWRITE, allowing untrusted data to replace local template state before file inclusion. No authentication or user interaction is required, but exploitation has high complexity and displays the targeted local file's output.
