CVE-2026-72574 in Pico
الملخص
بحسب MITRE • 10/08/2026
A host header injection vulnerability in picocms/Pico through 2.1.4 allows an unauthenticated remote attacker to control the origin of JavaScript and CSS assets loaded by the default theme. When base_url is unset (the default), Pico::getBaseUrl() in lib/Pico.php builds the base URL from unvalidated Host, X-Forwarded-Host, X-Forwarded-Proto, and X-Forwarded-Port request headers. The resulting URL propagates to theme_url, assets_url, and plugins_url, causing script and stylesheet tags to load resources from an attacker-controlled domain.
