XSS/CSRF Remote Code Execution in XWiki.ConfigurableClass
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-cp3j-273x-3jxc 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 377,166 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
There is a reflected XSS or also direct remote code execution vulnerability in the code for displaying configurable admin sections. The code that can be passed through a URL parameter is only executed when the user who is visiting the crafted URL has edit right on at least one configuration section. While any user of the wiki could easily create such a section, in this case it is much more convenient to exploit GHSA-qj86-p74r-7wp5 which is why this attack scenario won't be further considered in the following. In contrast to GHSA-qj86-p74r-7wp5, this vulnerability doesn't require the attacker to have an account or any access on the wiki. It is sufficient to trick any admin user of the XWiki installation to visit the crafted URL. Alternatively, the URL can also be embedded as image source of an image in any content of the wiki like a comment that could be left by an anonymous user. This vulnerability allows full remote code execution with programming rights and thus impacts the confidentiality, integrity and availability of the whole XWiki installation.
Patches
This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1
Workarounds
The patch can be manually applied to the document XWiki.ConfigurableClass.

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-administration-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-administration-ui to 14.10.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cp3j-273x-3jxc 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-cp3j-273x-3jxc can be triaged on real exposure rather than presence alone.
Tailored to GHSA-cp3j-273x-3jxc. 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-cp3j-273x-3jxc in your dependencies?
O3 Security finds GHSA-cp3j-273x-3jxc across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
