Threat metrics

Exploit Maturity: POC

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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Sep 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 2026-10-25.

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

European organizations should prioritize the following mitigation steps: 1) Immediately audit all Total.js CMS installations to identify affected versions (19.0 through 19.9.0). 2) Apply any available patches or updates from Total.js as soon as they are released. In absence of official patches, implement input validation and output encoding on the Files Menu component to sanitize user inputs and prevent script injection. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the CMS. 4) Educate users and administrators about the risks of clicking untrusted links and the importance of verifying URLs, to reduce the risk of successful user interaction exploitation. 5) Monitor web server and application logs for unusual or suspicious requests targeting the Files Menu or related endpoints. 6) Consider deploying Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the CMS environment. 7) Regularly review and update incident response plans to include scenarios involving XSS exploitation. These steps go beyond generic advice by focusing on specific components and practical controls tailored to this vulnerability.

Description

A vulnerability has been found in Total.js CMS up to 19.9.0. This impacts an unknown function of the component Files Menu. The manipulation leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using Total.js CMS, this vulnerability poses a moderate risk. Exploitation could lead to unauthorized actions performed in the context of legitimate users, potentially exposing sensitive data or enabling phishing attacks. Organizations in sectors such as government, finance, healthcare, and e-commerce, where CMS platforms are used to manage public-facing or internal content, could face reputational damage, regulatory penalties under GDPR if personal data is compromised, and operational disruptions. The remote nature of the attack vector means that attackers do not need physical access or insider privileges, increasing the threat landscape. However, the requirement for user interaction limits automated exploitation, somewhat reducing the immediacy of the threat. Still, targeted spear-phishing or social engineering campaigns could leverage this vulnerability effectively. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially given the public disclosure.
