Published: 05 January 2026
Summary
CVE-2026-0589 is a medium-severity Improper Authentication (CWE-287) vulnerability in Fabian Online Product Reservation System. 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 33.4th 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 AC-3 (Access Enforcement) and IA-2 (Identification and Authentication (Organizational Users)).
Deeper analysis
CVE-2026-0589 is an improper authentication vulnerability (CWE-287) in code-projects Online Product Reservation System 1.0, affecting an unknown function within the Administration Backend component. The issue allows manipulation leading to authentication bypass and was published on 2026-01-05 with 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 low complexity.
Remote attackers require no privileges or user interaction to exploit this vulnerability, potentially gaining unauthorized access to the administration backend. Successful exploitation could result in limited impacts to confidentiality, integrity, and availability, as reflected in the CVSS metrics, enabling actions such as administrative actions without valid credentials.
Advisories reference a publicly available proof-of-concept exploit on GitHub detailing authentication bypass for the admin panel, hosted at https://github.com/foeCat/CVE/blob/main/OnlineProductReservation_PHP/auth_bypass_admin_panel.md and its POC section. Additional details are available via VulDB (https://vuldb.com/?ctiid.339499 and https://vuldb.com/?id.339499) and the project site (https://code-projects.org/), though no specific patches or mitigations are detailed in the provided information.
