XWiki Platform allows remote code execution as guest via SolrSearchMacros requestGHSA-rr6p-3pfg-562j
CRITICALFix: xwiki/xwiki-platform@67021dbGHSA-rr6p-3pfg-562j is a critical-severity (CVSS 9.8) CWE-95 vulnerability in org.xwiki.platform:xwiki-platform-search-solr-ui. It is in CISA's Known Exploited Vulnerabilities catalog (added 2025-10-30) — treat it as actively exploited and patch now. A fix is available for org.xwiki.platform:xwiki-platform-search-solr-ui — see the affected versions and patch details below.
Exploitation Status
Actively exploited in the wild
- Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2025-10-30. Federal agencies were required to remediate by 2025-11-20.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
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 <host>/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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-search-solr-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-search-solr-ui to 15.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rr6p-3pfg-562j is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
