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 31 Dec 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

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.

AI-suggested

1. Immediately implement strict input validation and sanitization on all user inputs processed by the Notice Handler component, especially in the affected src/views/system/notice/index.vue file. 2. Deploy a robust Content Security Policy (CSP) that restricts the execution of inline scripts and limits sources of executable code to trusted domains. 3. Monitor web application logs and network traffic for unusual or suspicious activity indicative of XSS exploitation attempts. 4. Educate users and administrators about the risks of clicking unknown links or interacting with untrusted notices within the admin interface. 5. If feasible, temporarily disable or restrict access to the Notice Handler functionality until an official patch is released. 6. Keep all dependencies and frameworks up to date, and subscribe to vendor or community advisories for updates on patches. 7. Consider implementing Web Application Firewalls (WAF) with rules designed to detect and block XSS payloads targeting this component. 8. Conduct regular security assessments and penetration testing focusing on web interface vulnerabilities. 9. Prepare incident response plans to quickly address any exploitation attempts. 10. Engage with the vendor or community to encourage timely patch development and disclosure.

Description

A weakness has been identified in youlaitech vue3-element-admin up to 3.4.0. This issue affects some unknown processing of the file src/views/system/notice/index.vue of the component Notice Handler. This manipulation causes cross site scripting. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be exploited. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, exploitation of CVE-2025-15372 could lead to unauthorized access to sensitive information, session hijacking, and manipulation of administrative functions within web applications using vue3-element-admin. This could result in data breaches, loss of user trust, and potential regulatory penalties under GDPR if personal data is compromised. The vulnerability could be leveraged to conduct further attacks within the network, such as lateral movement or privilege escalation, especially if the admin panel controls critical infrastructure or sensitive business functions. The medium severity score indicates moderate risk, but the availability of public exploits and lack of vendor patching increase the urgency. Organizations in sectors like finance, healthcare, and government, which often deploy web admin panels for internal management, are particularly at risk. The impact on availability is limited, but the confidentiality and integrity risks are significant enough to warrant immediate attention. Additionally, the vulnerability could be used as a foothold for more complex attacks, amplifying its potential damage.

Summary

CVE-2025-15372 is a cross-site scripting vulnerability identified in the youlaitech vue3-element-admin product, affecting versions 3.0 through 3.4.0. The vulnerability exists due to improper handling of user-controllable input in the Notice Handler component, specifically within the source file src/views/system/notice/index.vue. This flaw allows remote attackers to inject malicious JavaScript code that executes in the context of the victim's browser when they interact with the affected notice interface. The attack vector is network-based with low attack complexity, requiring no authentication but necessitating user interaction, such as clicking a malicious link or viewing a crafted notice. The vulnerability impacts confidentiality and integrity by enabling theft of session tokens, credentials, or performing unauthorized actions on behalf of the user. The vendor was notified but has not issued a patch or response, and public exploit code is available, increasing the risk of exploitation. The CVSS 4.0 score of 4.8 reflects a medium severity, considering the ease of exploitation and potential impact. No known exploits in the wild have been reported yet, but the availability of exploit code means attackers could leverage this vulnerability soon. The lack of vendor response and patch availability means organizations must implement interim mitigations. The vulnerability is particularly relevant for organizations using vue3-element-admin as part of their web administration interfaces, especially those relying on the affected versions. Given the widespread use of Vue.js frameworks in Europe, this vulnerability could have broad implications if not addressed.
