To Reproduce

Risk: CRITICAL Affacted Paths: zhk-hnw-web\axa-next\node_modules\next\dist\compiled\jsonwebtoken\index.js zhk-hnw-web\axa-next\node_modules\next\dist\compiled\babel-packages\packages-bundle.js CVE: CVE-2026-4800 CWE: CWE-94 Improper Control of Generation of Code ('Code Injection') Issues Details Impact: The fix for CVE-2021-23337 (https://github.com/advisories/GHSA-35jh-r3h4-6jhm) added validation for the variable option in _.template but did not apply the same validation to options.imports key names. Both paths flow into the same Function() constructor sink. When an application passes untrusted input as options.imports key names, an attacker can inject default-parameter expressions that execute arbitrary code at template compilation time. Additionally, _.template uses assignInWith to merge imports, which enumerates inherited properties via for..in. If Object.prototype has been polluted by any other vector, the polluted keys are copied into the imports object and passed to Function(). Patches: Users should upgrade to version 4.18.0. Workarounds: Do not pass untrusted input as key names in options.imports. Only use developer-controlled, static key names.

We are preparing to launch our official information website. However, the security team has flagged a critical vulnerability that must be resolved before deployment. Although we have noted that this issue cannot be directly triggered or exploited through any website touchpoints, the launch is currently on hold until it is addressed
