CVE-2023-29044Network attack vector

Authenticated script execution via unescaped imageData

Published Nov 2, 2023 · Updated Aug 2, 2024

Cross-site scripting in OX App Suite office 7.10.6-rev7 allows remote authenticated users to run script code in collaborators' browsers. The collaboration service accepts an imageData value with an invalid data type and passes it to active collaborators without escaping it. Exploitation requires a crafted document operation, an authenticated session, and another user actively collaborating on the same document, exposing that user's browser context to script execution.
