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

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 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.

What to do

AI-suggested

1. Implement strict input validation and output encoding on all user-supplied data, especially the 'First Name' field and other parameters in /student-view.php. 2. Deploy a Web Application Firewall (WAF) configured to detect and block common XSS attack patterns targeting the school management system. 3. Conduct thorough code reviews and security testing focusing on input handling in all components of the application. 4. Isolate the school management system within a segmented network zone to limit lateral movement if compromised. 5. Monitor logs and user activity for unusual behavior indicative of exploitation attempts. 6. Educate administrative users about the risks of clicking on suspicious links or executing untrusted scripts. 7. If possible, apply temporary patches or workarounds such as disabling the vulnerable input fields or restricting editing privileges until an official fix is released. 8. Engage with the vendor or consider alternative solutions if timely remediation is not forthcoming.

Description

A weakness has been identified in codingWithElias School Management System up to f1ac334bfd89ae9067cc14dea12ec6ff3f078c01. Affected is an unknown function of the file /student-view.php of the component Edit Student Info Page. This manipulation of the argument First Name causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be exploited. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. Other parameters might be affected as well. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, particularly educational institutions using the codingWithElias School Management System, this vulnerability poses a risk to confidentiality, integrity, and availability of sensitive student and administrative data. Attackers exploiting this XSS flaw could hijack user sessions, leading to unauthorized access to personal information, grades, and other protected records. The integrity of student data could be compromised by unauthorized modifications. Additionally, attackers could use the vulnerability as a foothold to deploy further attacks such as phishing or malware distribution within the school network. The lack of vendor response and absence of patches increase exposure time, raising the risk of targeted attacks. Disruption of school management operations could impact educational delivery and compliance with data protection regulations such as GDPR, potentially resulting in legal and financial consequences.

Summary

CVE-2025-13795 identifies a cross-site scripting vulnerability in the codingWithElias School Management System, affecting versions up to commit f1ac334bfd89ae9067cc14dea12ec6ff3f078c01. The vulnerability exists in the /student-view.php file, specifically on the Edit Student Info Page, where the 'First Name' parameter is not properly sanitized or encoded before being reflected in the web page. This allows an attacker to inject malicious JavaScript code that executes in the context of the victim's browser. The vulnerability is remotely exploitable without requiring authentication, although user interaction is necessary to trigger the payload. The product uses a rolling release model, complicating version tracking and patch management. The vendor has not responded to disclosure attempts, and no official patches or updates have been released. Public exploit code is available, increasing the likelihood of exploitation. The vulnerability can be leveraged to steal session cookies, perform actions on behalf of authenticated users, or deliver further malware. Given the nature of school management systems, exploitation could compromise sensitive student and staff data, disrupt operations, or damage institutional reputation.
