Upgrade org.xwiki.platform:xwiki-platform-rest-server to version 14.10.8, 15.2 or higher.
Overview
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). The REST API allows executing all actions via POST requests and accepts text/plain, multipart/form-data or application/www-form-urlencoded as content types which can be sent via regular HTML forms. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation.
Note:
For regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari.
Workaround
It is possible to check for the Origin header in a reverse proxy to protect the REST endpoint from CSRF attacks, see the Jira issue for an example configuration.
