CVE-2023-26477
March 02, 2023
XWiki Platform is a generic wiki platform. Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the "newThemeName" request parameter (URL parameter), in combination with additional parameters. This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6. As a workaround, it is possible to edit "FlamingoThemesCode.WebHomeSheet" and manually perform the changes from the patch fixing the issue.
