Published: 05 January 2026
Summary
CVE-2026-0590 is a medium-severity Injection (CWE-74) vulnerability in Fabian Online Product Reservation System. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 23.1th 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-6 (Least Privilege).
Deeper analysis
CVE-2026-0590 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Online Product Reservation System 1.0. The flaw affects an unknown function in the file /app/checkout/delete.php within the POST Parameter Handler component, where manipulation of the POST argument "ID" triggers the injection.
The vulnerability is remotely exploitable over the network with low attack complexity and no user interaction required, but demands low privileges (PR:L) from the attacker. Exploitation yields low impacts on confidentiality, integrity, and availability (CVSS 6.3: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). A proof-of-concept exploit has been publicly disclosed and may be utilized.
Advisories and additional details, including the PoC, are available via VulDB (ctiid.339500, id.339500), a GitHub repository at github.com/foeCat/CVE with the file sqli_checkout_delete.php.md, and the project site at code-projects.org. No specific patches are detailed in the provided references.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of the untrusted POST 'ID' parameter before it reaches the SQL query in delete.php, blocking the CWE-89 injection.
Enforces least-privilege assignment so that only the minimal accounts needed for checkout operations can reach the vulnerable delete.php endpoint, reducing the attack surface.
Enables monitoring of database query patterns and anomalies that would reveal attempted or successful exploitation of the ID parameter in checkout/delete.php.
