CVE-2023-29527: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

April 20, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions a user without script or programming right may edit a user profile (or any other document) with the wiki editor and add groovy script content. Viewing the document after saving it will execute the groovy script in the server context which provides code execution. This vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.3. Users are advised to upgrade. There are no known workarounds for this issue.
