CVE-2023-50883

medium

Description

ONLYOFFICE Docs before 8.0.1 allows XSS because a macro is an immediately-invoked function expression (IIFE), and therefore a sandbox escape is possible by directly calling the constructor of the Function object. NOTE: this issue exists because of an incorrect fix for CVE-2021-43446.
