CVE-2023-37910: org.xwiki.platform:xwiki-platform-attachment-api vulnerable to Missing Authorization on Attachment Move
First published: Wed Oct 25 2023(Updated: )
### Impact An attacker with edit access on any document (can be the user profile which is editable by default) can move any attachment of any other document to this attacker-controlled document.

Further, the attachment is deleted from the source document. This vulnerability exists since the introduction of attachment move support in XWiki 14.0 RC1. ### Patches This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1. ### Workarounds There is no workaround apart from upgrading to a fixed version. ### References * https://jira.xwiki.org/browse/XWIKI-20334 * https://github.com/xwiki/xwiki-platform/commit/d7720219d60d7201c696c3196c9d4a86d0881325 ### 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:security@xwiki.org) ### Attribution This vulnerability has been reported on Intigriti by [Mete](https://www.linkedin.com/in/metehan-kalkan-5a3201199).
