CVE-2023-29043Network attack vector

Script execution via unescaped imageSrc operation data

Published Nov 2, 2023 · Updated Dec 3, 2024

Cross-site scripting in OX App Suite office through 7.10.6-rev7 allows remote attackers to run script code through crafted presentations. The presentation editor processes user-controlled imageSrc operation data without escaping it, allowing embedded script to execute when a collaborator copies affected content. Execution requires an actively collaborating user to perform a triggering edit action and runs in that user's browser context.
