MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk8th percentile — higher than 8% of all known CVEs
Summary
Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7 accept protocol-relative paths such as //evil.com in the reloadNuxtApp function. These paths pass the script-protocol check but resolve to a cross-origin URL against the current page protocol.
Risk Assessment
Attackers can inject paths like //evil.com to redirect users to attacker-controlled hosts, enabling phishing and OAuth authorization-code theft.
Recommendation
It is recommended to update Nuxt to version 4.4.7 or 3.21.7 to mitigate this vulnerability. Additionally, conducting a code audit to identify and eliminate potential security flaws is advisable.
