CVE-2023-28154: Cross-realm object access in Webpack 5

March 13, 2023 (updated November 7, 2023)

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.
