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

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

To mitigate CVE-2026-3702, organizations should first check for any official patches or updates from SourceCodester and apply them promptly once available. In the absence of patches, implement input validation and output encoding on the 'page' parameter to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Additionally, use web application firewalls (WAFs) configured to detect and block XSS attack patterns targeting the vulnerable parameter. Educate users about the risks of clicking on suspicious links and encourage the use of updated browsers with built-in XSS protections. Regularly audit and monitor web server logs for unusual requests targeting the 'page' parameter. Finally, consider isolating or restricting access to the affected application to trusted networks until a permanent fix is applied.

Description

A vulnerability was detected in SourceCodester Loan Management System 1.0. Affected by this issue is some unknown functionality of the file /index.php. Performing a manipulation of the argument page results in cross site scripting. The attack is possible to be carried out remotely. The exploit is now public and may be used.

Impact

The primary impact of CVE-2026-3702 is on the confidentiality and integrity of user data within the affected loan management system. Successful exploitation can lead to session hijacking, allowing attackers to impersonate legitimate users and potentially access sensitive financial information or perform unauthorized transactions. It can also facilitate phishing attacks by redirecting users to malicious sites or injecting deceptive content. Although the vulnerability does not directly compromise system availability, the resulting trust erosion and potential data breaches can have significant operational and reputational consequences for organizations. Financial institutions and businesses relying on SourceCodester Loan Management System 1.0 may face regulatory scrutiny and customer loss if exploited. The ease of exploitation and remote attack vector increase the likelihood of attacks, especially since exploit code is publicly available. However, the requirement for user interaction somewhat limits mass exploitation. Overall, the threat poses a moderate risk to organizations handling sensitive loan and financial data.

Summary

CVE-2026-3702 is a cross-site scripting vulnerability identified in SourceCodester Loan Management System version 1.0. The vulnerability resides in the /index.php file, specifically in the handling of the 'page' parameter. An attacker can craft a malicious URL that manipulates this parameter to inject arbitrary JavaScript code, which executes in the context of the victim's browser when they visit the manipulated link. This type of vulnerability is classified as reflected XSS, as the malicious payload is reflected off the web server in the response. The attack vector is network-based (remote), requiring no authentication, but user interaction is necessary to trigger the payload. The vulnerability does not affect the confidentiality, integrity, or availability of the system directly but can be leveraged to steal session cookies, perform actions on behalf of the user, or redirect users to malicious websites, thereby compromising user data and trust. The CVSS 4.0 vector indicates low attack complexity and no privileges required, but user interaction is needed. No patches or official fixes have been linked yet, and while no known exploits are reported in the wild, the public availability of exploit code increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which may limit exposure depending on the adoption of this version.
