CVE-2026-3757 is a medium-severity Injection (CWE-74) vulnerability in Projectworlds Online Art Gallery Shop. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-3757 is a SQL injection vulnerability (CWE-74, CWE-89) in projectworlds Online Art Gallery Shop 1.0. The issue affects an unknown functionality exposed via the /?pass=1 file or endpoint, where manipulation of the 'fnm' argument triggers the injection. Published on 2026-03-08, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and ease of exploitation.
Unauthenticated remote attackers can exploit this vulnerability with low attack complexity and no user interaction. By crafting malicious input for the 'fnm' parameter, attackers may execute arbitrary SQL queries, potentially leading to low-level impacts on confidentiality (e.g., data exposure), integrity (e.g., data alteration), and availability (e.g., denial of service). An exploit for this vulnerability has been publicly released, increasing the risk of widespread attacks against exposed instances.
Advisories and further details are available in the referenced sources, including a GitHub issue at https://github.com/hmkunlun/projectworldcve/issues/1 and VulDB entries at https://vuldb.com/?ctiid.349735, https://vuldb.com/?id.349735, and https://vuldb.com/?submit.768057. No specific patches or mitigations are detailed in the initial disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of the 'fnm' input parameter to block crafted SQL payloads before they reach the database.
Enforces that only authorized queries and data accesses are permitted, limiting the ability of an unauthenticated remote attacker to execute arbitrary SQL.
Enables monitoring and analysis of application inputs and database queries to identify anomalous patterns indicative of SQL injection attempts.
