ONLYOFFICE Docs before 8.1.0 allows XSS via a GeneratorFunction Object attack against a macro. This is related to use of an immediately-invoked function expression (IIFE) for a macro. NOTE: this issue exists because of an incorrect fix for CVE-2021-43446 and CVE-2023-50883.

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.

ONLYOFFICE all versions as of 2021-11-08 is vulnerable to Cross Site Scripting (XSS). The "macros" feature of the document editor allows malicious cross site scripting payloads to be used.
