Cross-realm object access in Webpack 5

Description

Webpack 5 before 5.76.0 does not avoid cross-realm object access. ImportParserPlugin.js mishandles the magic comment feature. An attacker who controls a property of an untrusted object can obtain access to the real global object.

Recommendation

Update the webpack package to the latest compatible version. Followings are version details:

• Affected version(s): >= 5.0.0, < 5.76.0
• Patched version(s): 5.76.0
