CVE-2026-25557 Evoluted CVE debrief

CVE-2026-25557 is a reflected cross-site scripting vulnerability in Evoluted PHP Directory Listing Script through 4.0.5. The vulnerability exists in the index.php file where the dir parameter value is reflected without HTML encoding inside the HTML title element and inside anchor href attributes in the breadcrumb navigation. This allows attackers to inject arbitrary JavaScript via crafted dir parameter values by breaking out of the title context or injecting event handlers into breadcrumb anchor attributes to execute malicious scripts in a victim's browser.
