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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

1. Immediate Upgrade: Organizations should upgrade affected XWiki Platform versions to the fixed releases 16.4.7, 16.10.3, or 17.0.0 or later. This is the most effective mitigation.

2. Access Control Review: Review and tighten access control policies on XClass definitions and page properties to ensure that sensitive metadata is not exposed to unauthorized users.

3. Wiki Configuration Audit: Audit wiki page naming conventions and metadata exposure. Avoid using sensitive or confidential information in page titles or names.

4. REST API Monitoring: Implement monitoring and logging of REST API access to detect unusual or unauthorized requests that attempt to enumerate page titles.

5. Network Segmentation: Restrict access to the XWiki REST API endpoints to trusted networks or VPNs where possible to reduce exposure to external attackers.

6. Incident Response Preparedness: Prepare to respond to potential information disclosure incidents by having processes to assess the scope of leaked information and notify affected parties if necessary.

7. User Awareness: Educate wiki administrators and users about the risks of exposing sensitive information in page titles and encourage best practices for information classification.

These mitigations go beyond generic patching advice by emphasizing configuration audits, monitoring, and operational controls tailored to the nature of the vulnerability.

Description

XWiki is a generic wiki platform. In XWiki Platform versions 10.9 through 16.4.6, 16.5.0-rc-1 through 16.10.2, and 17.0.0-rc-1, the title of every single page whose reference is known can be accessed through the REST API as long as an XClass with a page property is accessible, this is the default for an XWiki installation. This allows an attacker to get titles of pages whose reference is known, one title per request. This doesn't affect fully private wikis as the REST endpoint checks access rights on the XClass definition. The impact on confidentiality depends on the strategy for page names. By default, page names match the title, so the impact should be low but if page names are intentionally obfuscated because the titles are sensitive, the impact could be high. This has been fixed in XWiki 16.4.7, 16.10.3 and 17.0.0 by adding access control checks before getting the title of any page.

Impact

For European organizations using XWiki Platform, this vulnerability poses a confidentiality risk that varies based on internal wiki configuration and usage. Organizations that rely on XWiki for collaboration, documentation, or knowledge management may inadvertently expose sensitive project names, internal documentation titles, or other metadata that could aid attackers in reconnaissance or social engineering. This is particularly concerning for sectors handling sensitive data such as finance, healthcare, government, and critical infrastructure, where even metadata leakage can have regulatory and operational consequences.

Since the vulnerability does not require authentication or user interaction, it can be exploited remotely by unauthenticated attackers, increasing the attack surface. Although the vulnerability does not directly impact integrity or availability, the exposure of sensitive information could facilitate further targeted attacks or data breaches. The impact is mitigated in fully private wikis but remains significant for default or partially restricted installations.

Given the high CVSS score and the widespread use of XWiki in European enterprises and public institutions, the vulnerability could lead to reputational damage, compliance violations (e.g., GDPR if sensitive personal data is indirectly exposed), and increased risk of follow-on attacks. Organizations with complex or sensitive wiki content should prioritize assessment and remediation.
