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: 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: 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 19 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
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 2026-10-26.

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. Immediate mitigation should include implementing strict input validation and output encoding on all user-supplied data processed by /market/chatuser.php to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. 3. If possible, disable or restrict the chat functionality or any feature that processes user input in the affected component until a vendor patch is available. 4. Monitor web server and application logs for unusual or suspicious requests targeting /market/chatuser.php or containing script tags and other XSS indicators. 5. Educate users to avoid clicking on suspicious links or interacting with untrusted content within the application. 6. Follow up with the vendor for official patches or updates and apply them promptly once released. 7. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting this specific endpoint. 8. Conduct regular security assessments and code reviews focusing on input handling and sanitization practices in the application.

Description

A flaw has been found in code-projects Simple Stock System 1.0. The impacted element is an unknown function of the file /market/chatuser.php. This manipulation causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been published and may be used.

Impact

The primary impact of this XSS vulnerability is on the integrity and trustworthiness of the affected web application and its users. Attackers can inject malicious scripts that execute in the browsers of users interacting with the vulnerable component, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, and unauthorized actions performed on behalf of users. Although the confidentiality impact is rated none, the indirect consequences of stolen session tokens or credentials can lead to broader data breaches. The availability of the system is not affected. The exploitation requires user interaction, which somewhat limits the attack scope, but the remote attack vector and lack of authentication requirements increase the risk. Organizations relying on Simple Stock System 1.0 may face reputational damage, loss of customer trust, and potential regulatory consequences if user data is compromised. The presence of published exploit code raises the urgency for mitigation to prevent opportunistic attacks.
