Detailsinfo

A vulnerability classified as problematic has been found in xwiki xwiki-platform up to 15.10.12/16.4.3/16.7.x. Affected is the function xcontext.dropPermissions. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on integrity, and availability. CVE summarizes:

XWiki is a generic wiki platform. In versions starting from 4.5.1 to before 15.10.13, from 16.0.0-rc-1 to before 16.4.4, and from 16.5.0-rc-1 to before 16.8.0-rc-1, the Solr script service doesn't take dropped programming rights into account. The Solr script service that is accessible in XWiki's scripting API normally requires programming rights to be called. Due to using the wrong API for checking rights, it doesn't take the fact into account that programming rights might have been dropped by calling `$xcontext.dropPermissions()`. If some code relies on this for the safety of executing Velocity code with the wrong author context, this could allow a user with script rights to either cause a high load by indexing documents or to temporarily remove documents from the search index. This issue has been patched in versions 15.10.13, 16.4.4, and 16.8.0-rc-1.
