Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the webpack package, which could allow a remote attacker to bypass security restrictions caused by the mishandling of the magic comment feature by the ImportParserPlugin.js. This flaw allows an attacker to gain access to the real global object by sending a specially-crafted request.

Description Sandipan Roy 2023-03-17 05:33:16 UTC 
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.
