Summary
CVE-2026-30529 is a high-severity SQL Injection (CWE-89) vulnerability in Oretnom23 Online Food Ordering System. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.5th 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 SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-30529, published on 2026-03-27, is a SQL injection vulnerability (CWE-89) affecting SourceCodester Online Food Ordering System version 1.0. The flaw exists in the Actions.php file, specifically within the save_user action, where the application fails to properly sanitize user-supplied input in the "username" parameter. This allows attackers to inject malicious SQL commands. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity.
An authenticated attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and without requiring user interaction (UI:N). Exploitation enables high-impact compromises to confidentiality, integrity, and availability (C:H/I:H/A:H), potentially allowing arbitrary SQL command execution to extract sensitive data, modify database contents, or disrupt system availability.
A proof-of-concept demonstrating the SQL injection via the username parameter is available at https://github.com/meifukun/Web-Security-PoCs/blob/main/Online-Food-Ordering-System/SQLi-Actions-saveUser-username.md. No vendor advisories or patches are detailed in the CVE references.
