CVE-2023-50883
Last modified
CVE-2023-50883 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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.. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
