HIGH 8.8

DescriptionGitHub Advisory

XWiki is an open-source wiki software platform. Any XWiki user with edit right on at least one App Within Minutes application (the default for all users XWiki) can obtain programming right/perform remote code execution by editing the application. This vulnerability has been fixed in XWiki 17.0.0, 16.4.7, and 16.10.3.

Executive ViewAI

Why It Matters

Any XWiki user with basic editing permissions can escalate privileges to gain complete system control and execute arbitrary code on affected servers. This is a critical remote code execution vulnerability that affects all XWiki deployments where users have default editing rights, creating an immediate risk of data breach, system compromise, and operational disruption.

Business Impact: High

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: disable App Within Minutes feature globally; restrict edit permissions to administrative users only; isolate XWiki instances from production networks; implement Web Application Firewall (WAF) rules to monitor for suspicious application editing activity; enable comprehensive audit logging and alert on privilege escalation attempts.
