CVE-2023-26475: XWIKI-20384: Use the new textarea restricted setup in comments · xwiki/xwiki-platform@d87d7bf
XWiki Platform is a generic wiki platform. Starting in version 2.3-milestone-1, the annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document. This has been patched in XWiki 13.10.11, 14.4.7 and 14.10. There is no easy workaround except to upgrade.

### Impact The annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document. To reproduce: add an annotation with the content `{{groovy}}print "hello"{{/groovy}}` and click the yellow scare to get a display of the annotation inline. The result is "hello" but it should be an error suggesting that it's not allowed to use the groovy macro. ### Patches This has been patched in XWiki 13.10.11, 14.4.7 and 14.10. ### Workarounds There is no easy workaround except to upgrade. ### References https://jira.xwiki.org/browse/XWIKI-20360 https://jira.xwiki.org/browse/XWIKI-20384 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:[email protected]) ### Attribution This vulnerability has been reported by René de Sain @renniepak.
