Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate this vulnerability, European organizations should immediately upgrade xwiki-pro-macros to version 1.27.1 or later, where the missing authorization check has been implemented. Until the upgrade is applied, restrict access to XWiki instances to trusted users only and limit macro execution permissions to highly trusted administrators. Conduct an audit of existing macros and Velocity scripts to identify and disable any potentially unsafe or unnecessary macros. Implement network segmentation and firewall rules to limit external access to XWiki servers. Monitor logs for unusual macro execution patterns or unauthorized access attempts. Employ application-layer security controls such as Web Application Firewalls (WAFs) with custom rules to detect and block suspicious Velocity script execution. Finally, educate administrators and developers about secure macro usage and the risks of executing untrusted code within XWiki environments.

Description

XWiki Remote Macros provides XWiki rendering macros that are useful when migrating content from Confluence. Prior to 1.27.1, the macro executes Velocity from the details pages without checking for permissions, which can lead to remote code execution. This vulnerability is fixed in 1.27.1.

Impact

For European organizations, the impact of CVE-2025-65036 can be severe, especially for those relying on XWiki for collaborative documentation, knowledge management, and content migration from Confluence. Successful exploitation could lead to unauthorized remote code execution, enabling attackers to access sensitive data, modify or delete content, and disrupt business operations. This could result in data breaches, intellectual property theft, and reputational damage. Organizations in regulated industries such as finance, healthcare, and government sectors face additional compliance risks due to potential violations of GDPR and other data protection laws. The vulnerability's ease of exploitation and network accessibility increase the likelihood of targeted attacks or opportunistic exploitation by cybercriminals. Additionally, compromised systems could serve as footholds for further attacks within the organization's network, amplifying the overall risk.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
