CVE-2025-24893: XWiki Platform Eval Injection Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run XWiki Platform. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-10-30, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-11-20; treat that as the outer limit, not the target.
• EPSS 99.9%, percentile 100.0: FIRST’s model estimates a 99.9% chance of exploitation activity in the next 30 days, higher than 100.0% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes org.xwiki.platform:xwiki-platform-search-solr-ui (Maven) >= 5.3-milestone-2, < 15.10.11, fixed in 15.10.11; org.xwiki.platform:xwiki-platform-search-solr-ui (Maven) >= 16.0.0-rc-1, < 16.4.1, fixed in 16.4.1. Check your lockfile, including transitive dependencies.

What it is

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any guest can perform arbitrary remote code execution through a request to SolrSearch. This impacts the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an instance, without being logged in, go to /xwiki/bin/get/Main/SolrSearch?media=rss&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28"Hello%20from"%20%2B%20"%20search%20text%3A"%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20. If there is an output, and the title of the RSS feed contains Hello from search text:42, then the instance is vulnerable. This vulnerability has been patched in XWiki 15.10.11, 16.4.1 and 16.5.0RC1. Users are advised to upgrade. Users unable to upgrade may edit Main.SolrSearchMacros in SolrSearchMacros.xml on line 955 to match the rawResponse macro in macros.vm#L2824 with a content type of application/xml, instead of simply outputting the content of the feed.

From the GitHub advisory

Impact Any guest can perform arbitrary remote code execution through a request to SolrSearch. This impacts the confidentiality, integrity and availability of the whole XWiki installation.

To reproduce on an instance, without being logged in, go to /xwiki/bin/get/Main/SolrSearch?media=rss&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28"Hello%20from"%20%2B%20"%20search%20text%3A"%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20. If there is an output, and the title of the RSS feed contains Hello from search text:42, then the instance is vulnerable.

Patches This vulnerability has been patched in XWiki 15.10.11, 16.4.1 and 16.5.0RC1.

Workarounds This line in Main.SolrSearchMacros can be edited to match the rawResponse macro defined here with a content type of application/xml, instead of simply outputting the content of the feed.
