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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.

Exploitation evidence

CVE published 8 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

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

To mitigate CVE-2026-2158, organizations should immediately review and update the /check_user.php script to implement strict input validation and sanitization for the Username parameter. The preferred approach is to refactor the code to use parameterized queries or prepared statements to prevent SQL injection. If source code modification is not immediately feasible, deploying a web application firewall (WAF) with rules to detect and block SQL injection attempts targeting the Username parameter can provide temporary protection. Additionally, organizations should conduct thorough security assessments of the Student Web Portal and related systems, monitor database logs for suspicious queries, and restrict external access to the portal where possible. Regular backups of the database should be maintained to enable recovery in case of data tampering. Finally, organizations should track vendor updates or patches and apply them promptly once available.

Description

A vulnerability was detected in code-projects Student Web Portal 1.0. This impacts an unknown function of the file /check_user.php. Performing a manipulation of the argument Username results in sql injection. It is possible to initiate the attack remotely.

Impact

The primary impact of CVE-2026-2158 is the potential compromise of sensitive student data stored in the backend database of the Student Web Portal. Successful exploitation could allow attackers to extract confidential information such as personal details, academic records, or login credentials. Additionally, attackers might alter or delete data, disrupting the integrity and availability of the portal's services. This could lead to operational downtime, loss of trust, and regulatory compliance issues for educational institutions. Since the attack requires no authentication and can be performed remotely, the attack surface is broad, increasing the likelihood of exploitation if the system is exposed to the internet. Although no active exploits are known, the vulnerability presents a significant risk to organizations relying on this software, especially those with limited security monitoring or patch management capabilities.

Summary

CVE-2026-2158 identifies a SQL injection vulnerability in the code-projects Student Web Portal version 1.0, specifically within the /check_user.php script. The vulnerability arises from improper sanitization or validation of the Username parameter, allowing an attacker to inject arbitrary SQL code. This injection can be performed remotely without requiring authentication or user interaction, making exploitation straightforward. The vulnerability impacts the confidentiality, integrity, and availability of the underlying database by potentially enabling unauthorized data retrieval, modification, or deletion. The CVSS 4.0 base score is 6.9 (medium), reflecting the ease of exploitation (low attack complexity), no privileges required, and no user interaction needed, but with limited scope and impact on the system. No patches or known exploits are currently documented, indicating that the vulnerability may be newly disclosed or under limited active exploitation. The Student Web Portal is likely used by educational institutions to manage student information, making the data sensitive and critical. The lack of authentication requirement and remote attack vector increase the urgency for mitigation. The vulnerability underscores the importance of secure coding practices, particularly input validation and the use of parameterized queries to prevent SQL injection attacks.
