Detailsinfo A vulnerability classified as problematic has been found in xwiki xwiki-platform, xwiki-platform-legacy-oldcore and xwiki-platform-oldcore up to 17.4.7/17.10.0. This affects an unknown function of the component Velocity Scripting API. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is: XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.4.8 and 17.10.1, an improperly protected scripting API allows any user with script right to bypass the sandboxing of the Velocity scripting API and execute, e.g., arbitrary Python scripts, allowing full access to the XWiki instance and thereby compromising the confidentiality, integrity and availability of the whole instance. Note that script right already constitutes a high level of access that we don't recommend giving to untrusted users. This vulnerability is fixed in 17.4.8 and 17.10.1. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-33229 since 03/18/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. The exploitation requires an enhanced level of successful authentication. Neither technical details nor an exploit are publicly available. Upgrading to version 17.4.8 or 17.10.1 eliminates this vulnerability.
