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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: 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 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

Organizations should prioritize upgrading Cockpit installations to version 2.11.4 or later to remediate this vulnerability. Beyond patching, administrators should implement strict input validation and output encoding on all user-supplied data within the management interface to prevent XSS. Employing Content Security Policy (CSP) headers can mitigate the impact of potential XSS by restricting script execution sources. Additionally, monitoring web server logs for unusual requests to /system/users/save and anomalous user behavior can help detect exploitation attempts. Limiting access to the Cockpit interface via network segmentation, VPNs, or IP whitelisting reduces exposure to remote attackers. Regular security training for administrators to recognize phishing or social engineering attempts that might leverage this vulnerability is also recommended.

Description

A vulnerability was found in Cockpit up to 2.11.3. It has been rated as problematic. This issue affects some unknown processing of the file /system/users/save. The manipulation of the argument name/email leads to cross site scripting. The attack may be initiated remotely. Upgrading to version 2.11.4 is able to address this issue. The patch is named bdcd5e3bc651c0839c7eea807f3eb6af856dbc76. It is recommended to upgrade the affected component. The vendor was contacted early about this disclosure and acted very professional. A patch and new release was made available very quickly.

Impact

For European organizations, the impact of this vulnerability can be significant, especially for enterprises and service providers relying on Cockpit for server management. Successful exploitation could lead to session hijacking, unauthorized actions, or credential theft, potentially compromising server management operations. This could disrupt business continuity, lead to data breaches, or facilitate lateral movement within networks. Given that Cockpit is often used in Linux server environments common in European data centers and cloud infrastructures, the vulnerability could affect critical infrastructure management. The medium severity rating suggests that while the vulnerability is not catastrophic, it poses a tangible risk that could be exploited in targeted attacks, especially in sectors with high-value assets such as finance, healthcare, and government institutions across Europe.

Summary

CVE-2025-7053 is a cross-site scripting (XSS) vulnerability identified in Cockpit, a widely used web-based server management interface, affecting versions up to 2.11.3. The vulnerability arises from improper sanitization of user-supplied input in the /system/users/save endpoint, specifically in the 'name' and 'email' parameters. An attacker can craft malicious input that, when processed by the vulnerable endpoint, results in the injection and execution of arbitrary JavaScript code in the context of the victim's browser. This flaw is exploitable remotely without authentication, although it requires some level of user interaction (UI:P) to trigger the malicious payload. The CVSS 4.0 base score is 5.1 (medium severity), reflecting a network attack vector with low complexity, no privileges required, and limited impact on confidentiality and integrity, but some impact on availability and integrity at a low level. The vendor has addressed this issue promptly by releasing version 2.11.4, which patches the vulnerability. No known exploits are currently reported in the wild. The vulnerability could be leveraged to steal session tokens, perform actions on behalf of authenticated users, or conduct phishing attacks within the Cockpit management interface.
