Confidentiality: Low
Integrity: None
Availability: None

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Nov 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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.

What to do

AI-suggested

European organizations should immediately upgrade the XWiki AdminTools application-admintools component to version 1.1 or later, where the vulnerability is patched. If immediate upgrading is not feasible, administrators must manually restrict the view rights of the AdminTools space to the XWikiAdminGroup to prevent unauthorized access. Regularly audit user permissions on wiki spaces to ensure no unintended access is granted. Implement network-level access controls to limit exposure of the XWiki instance to trusted users or internal networks where possible. Monitor access logs for unusual or unauthorized access attempts to the AdminTools.SpammedPages page. Incorporate this vulnerability into vulnerability management and patching cycles to ensure timely remediation. Additionally, educate administrators about the risks of default permissions and the importance of least privilege principles in wiki and collaboration platforms.

Description

XWiki AdminTools integrates administrative tools for managing a running XWiki instance. Prior to version 1.1, users without admin rights have access to AdminTools.SpammedPages. View rights are not restricted only to admin users for AdminTools.SpammedPages. While no data is visible to non admin users, the page is still accessible. This issue has been patched in version 1.1. A workaround involves setting the view rights for the AdminTools space to be only available for the XWikiAdminGroup.

Impact

For European organizations using XWiki with the AdminTools application-admintools component in versions prior to 1.1, this vulnerability poses a moderate risk. While direct data leakage is not evident, unauthorized access to the AdminTools.SpammedPages page could enable attackers or unauthorized users to gain insights into the administrative structure or spam management processes, potentially aiding in targeted attacks or social engineering campaigns. Organizations in sectors with strict data protection regulations, such as finance, healthcare, or government, may face compliance risks if unauthorized access leads to further exploitation. Additionally, publicly accessible XWiki instances used for collaboration or documentation could be targeted by attackers to gather intelligence. The vulnerability's remote and unauthenticated nature increases exposure, especially for organizations with externally facing wiki services. However, the lack of integrity or availability impact limits the potential for direct disruption or data manipulation.

The architecture needs to access and modification attributes for files to only those users who actually require those actions.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
