CVE-2025-45406 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. A stored cross-site scripting (XSS) vulnerability in CodeIgniter4 v4.6.0 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the debugbar_time parameter. NOTE: this is disputed by the Supplier because attackers cannot influence the value of debugbar_time, and because debugbar-related data is automatically escaped by the CodeIgniter Parser class.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
