• Confidentiality Impact: High. Unauthorized users can access sensitive information.
• Integrity Impact: High. Unauthorized users can modify or delete data.
• Availability Impact: High. Unauthorized users can disrupt services.

The CVSS score of 9.9 indicates a critical vulnerability that requires immediate attention and remediation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• User Profile Manipulation: An attacker with edit rights can inject malicious code into their user profile.
• Page Editing: An attacker can inject malicious code into any editable page.

Exploitation Methods:

• Code Injection: By adding instances of XWiki.SearchSuggestConfig and XWiki.SearchSuggestSourceClass, an attacker can execute arbitrary code.
• Privilege Escalation: Once the attacker gains code execution capabilities, they can escalate privileges to gain full control over the XWiki installation.

3. Affected Systems and Software Versions

Affected Versions:

• XWiki Platform versions prior to 14.10.21, 15.5.5, and 15.10.2.

Unaffected Versions:
