Last modified
CVE-2026-72574 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
