XWiki Platform vulnerable to remote code execution from account via SearchSuggestConfigSheet
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-h63h-5c77-77p5.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-h63h-5c77-77p5 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Impact
Any user with edit right on any page can perform arbitrary remote code execution by adding instances of XWiki.SearchSuggestConfig and XWiki.SearchSuggestSourceClass to their user profile or any other page. This compromises the confidentiality, integrity and availability of the whole XWiki installation.
To reproduce on an instance, as a user without script nor programming rights, add an object of type XWiki.SearchSuggestConfig to your profile page, and an object of type XWiki.SearchSuggestSourceClass as well. On this last object, set both name and icon properties to $services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')") and limit and engine to {{/html}}{{async}}{{velocity}}$services.logging.getLogger("attacker").error("I got programming: $services.security.authorization.hasAccess('programming')"){{/velocity}}{{/async}}. Save and display the page. If the logs contain any message ERROR attacker - I got programming: true then the instance is vulnerable.
Patches
This vulnerability has been patched in XWiki 14.10.21, 15.5.5 and 15.10.2.

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-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-ui to 14.10.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h63h-5c77-77p5 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-h63h-5c77-77p5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-h63h-5c77-77p5. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-h63h-5c77-77p5 in your dependencies?
O3 Security finds GHSA-h63h-5c77-77p5 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
