Description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions a user without script or programming right may edit a user profile (or any other document) with the wiki editor and add groovy script content. Viewing the document after saving it will execute the groovy script in the server context which provides code execution. This vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.3. Users are advised to upgrade. There are no known workarounds for this issue.

Decided by Exploit code for this candidate, published in a reviewed catalogue or a GitHub repository with 5 or more stars, or in use per CISA or VulnCheck; not only a CISA verdict, a forecast, or nothing at all
Finding This CVE is not listed in CISA KEV or VulnCheck KEV, CISA Vulnrichment records no active exploitation, no reviewed exploit catalogue carries an entry for it, and no GitHub PoC repository for it has 5 or more stars. Nobody has published exploit code worth tracing, so it is not a candidate for a rule ahead of the ones where somebody has; an upstream fix path does exist, so the remediation half of the candidacy still holds. This is a statement about what has been published, not about whether the defect is reachable or serious.
Candidate fix https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgrg-qvpp-9vwr : the maintainers' own security advisory: names the version that fixes it, so the fix is the difference between two releases
