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: 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.
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 8 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.

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), 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

Organizations should immediately audit their deployment of projectworlds Online Art Gallery Shop version 1.0 and restrict external access to the vulnerable endpoint if possible. Implement web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the 'fnm' parameter. Employ input validation and parameterized queries or prepared statements in the application code to prevent injection flaws. Monitor logs for suspicious activity related to the /?pass=1 endpoint and the 'fnm' parameter. Conduct regular security assessments and penetration tests to identify similar injection points. Educate developers on secure coding practices to avoid injection vulnerabilities in future versions. Finally, maintain an incident response plan to quickly address any exploitation attempts.

Description

A security flaw has been discovered in projectworlds Online Art Gallery Shop 1.0. Affected by this vulnerability is an unknown functionality of the file /?pass=1. The manipulation of the argument fnm results in sql injection. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks.

Impact

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive customer data, modification or deletion of records, and disruption of service availability. This can result in data breaches, loss of customer trust, financial damage, and regulatory penalties for affected organizations. Since the vulnerability requires no authentication and can be exploited remotely, any exposed instance of the affected software is at risk. The impact extends to confidentiality, integrity, and availability of data, which are critical for e-commerce platforms handling transactions and personal information. The public availability of exploit code increases the likelihood of attacks, especially from opportunistic threat actors. Organizations using this software may face reputational damage and operational disruptions if exploited.

Summary

CVE-2026-3757 is a remote SQL injection vulnerability affecting projectworlds Online Art Gallery Shop version 1.0. The vulnerability is triggered by manipulating the 'fnm' parameter in a request to the /?pass=1 endpoint. This injection flaw allows an attacker to craft malicious SQL queries that the backend database executes, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability requires no authentication and no user interaction, making it highly accessible to remote attackers. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Despite the medium severity score of 6.9, the public release of exploit code increases the urgency for remediation. The affected product is niche software used for online art gallery shops, which may have limited but specific deployment in small to medium e-commerce businesses. No official patches or fixes have been published yet, and no known active exploitation has been reported, but the vulnerability is considered exploitable and dangerous due to its nature and accessibility.
