CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28154 – webpack JS package <= 5.75.0 - Sandbox Bypass
https://notcve.org/view.php?id=CVE-2023-28154
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. 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. • https://github.com/webpack/webpack/compare/v5.75.0...v5.76.0 https://github.com/webpack/webpack/pull/16500 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AU7BOXTBK3KDYSWH67ASZ22TUIOZ3X5G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PPSAXUTXBCCTAHTCX5BUR4YVP25XALQ3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U2AFCM6FFE3LRYI6KNEQWKMXMQOBZQ2D https://access.redhat.com/security/cve/CVE-2023&# • CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2018-14732
An issue was discovered in lib/Server.js in webpack-dev-server before 3.1.6. Attackers are able to steal developer's code because the origin of requests is not checked by the WebSocket server, which is used for HMR (Hot Module Replacement). Anyone can receive the HMR message sent by the WebSocket server via a ws://127.0.0.1:8080/ connection from any origin. Se ha descubierto un problema en lib/Server.js en webpack-dev-server en versiones anteriores a la 3.1.6. Los atacantes pueden robar el código del desarrollador porque el origen de las peticiones no es comprobado por el servidor WebSocket, utilizado para HMR (Hot Module Replacement). • https://blog.cal1.cn/post/Sniffing%20Codes%20in%20Hot%20Module%20Reloading%20Messages https://github.com/webpack/webpack-dev-server/commit/f18e5adf123221a1015be63e1ca2491ca45b8d10 https://github.com/webpack/webpack-dev-server/issues/1445 • CWE-20: Improper Input Validation •
