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.

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.

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. Since no official patch is available, consider isolating or decommissioning vulnerable instances until a vendor fix is released. 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.
