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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Subsequent 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

European organizations using the ServiceNow AI Platform should immediately apply the security updates and patches released by ServiceNow to remediate CVE-2025-11449. For self-hosted instances or uniquely configured environments, coordinate with ServiceNow support to ensure all relevant hotfixes are applied. Implement strict input validation and output encoding on any custom integrations or extensions interacting with the platform to reduce XSS risks. Educate users on the dangers of clicking unsolicited or suspicious links, especially those purporting to be from internal IT or ServiceNow communications, to mitigate social engineering vectors. Employ web security controls such as Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of potential XSS attacks. Monitor logs and user activity for unusual behavior that could indicate exploitation attempts. Regularly review and update incident response plans to include scenarios involving web application vulnerabilities like reflected XSS. Finally, maintain up-to-date asset inventories to quickly identify and patch all affected ServiceNow instances across the organization.

Description

CVE-2025-11449 is a reflected cross-site scripting (XSS) vulnerability in the ServiceNow AI Platform that allows attackers to execute arbitrary code in the browsers of users who click on maliciously crafted links. This vulnerability does not require authentication and can be exploited remotely with low complexity, but requires user interaction. ServiceNow has released security updates and patches to address this issue for both hosted and self-hosted customers. The vulnerability has a medium severity rating with a CVSS score of 5.3. There are no known exploits in the wild at this time. European organizations using ServiceNow AI Platform should promptly apply the provided updates to mitigate risk. Countries with significant ServiceNow adoption and critical infrastructure relying on this platform are at higher risk. The vulnerability impacts confidentiality and integrity by enabling code execution in user browsers, potentially leading to session hijacking or data theft.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of user sessions within the ServiceNow AI Platform. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, unauthorized data access, or manipulation of platform workflows. This can disrupt business processes and lead to data breaches, especially in organizations where ServiceNow is integrated with critical IT infrastructure or sensitive data repositories. The requirement for user interaction limits the scope somewhat, but phishing or social engineering campaigns could be used to lure users into clicking malicious links. The impact is heightened in sectors such as finance, healthcare, and government, where ServiceNow is commonly used and where data sensitivity is high. Additionally, the AI Platform’s integration with automated workflows could amplify the consequences of exploitation if malicious scripts trigger unauthorized actions. Although no active exploits are known, the medium severity rating and the platform’s critical role in enterprise environments warrant prompt remediation to avoid potential targeted attacks.
