影响与攻击场景翻译中…
Successful exploitation of this XSS vulnerability could lead to the unauthorized extraction of Nuxt authentication tokens. These tokens grant access to sensitive data and functionalities within the Nuxt.js application. An attacker could leverage these tokens to impersonate legitimate users, access restricted resources, and potentially compromise the entire application. The impact is particularly severe for applications relying on Nuxt Devtools for debugging and development workflows, as attackers could inject malicious scripts during development or testing phases.

缓解措施和替代方案翻译中…
The primary mitigation for CVE-2025-52662 is to immediately upgrade Nuxt Devtools to version 2.6.4 or later. If upgrading is not feasible due to compatibility issues or breaking changes, consider temporarily disabling or restricting access to Nuxt Devtools in production environments. While a direct WAF rule is unlikely to be effective against this XSS, carefully reviewing and sanitizing all user inputs within the Nuxt.js application remains a crucial defense-in-depth measure. After upgrading, verify the fix by attempting to trigger the vulnerable functionality and confirming that the authentication token is not exposed.
