Description

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 pass the script-protocol check but resolve to a cross-origin URL against the current page protocol. Attackers can inject paths like //evil.com to redirect users to attacker-controlled hosts, enabling phishing and OAuth authorization-code theft.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 3.21.73.0.0 ≤ v < 3.21.74.0.0 ≤ v < 4.4.74.0.0
Vendor states this is fixed in 3.21.7 (unaffected)
Vendor states this is fixed in 4.4.7 (unaffected)
v < 3.21.74.0.0 ≤ v < 4.4.7
Affected range stops below 3.21.7, so it looks safe — our inference, not a vendor statement
