Summary

XWiki is a generic wiki platform. From 8.2 and 7.4.5 until 17.1.0-rc-1, 16.10.4, and 16.4.7, pages can gain script or programming rights when they contain a link and the target of the link is renamed or moved. This might lead to execution of scripts contained in xobjects that should have never been executed. This vulnerability is fixed in 17.1.0-rc-1, 16.10.4, and 16.4.7.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
