CVE-2026-5257
Published: 01 April 2026
Summary
CVE-2026-5257 is a medium-severity Injection (CWE-74) vulnerability in Code-Projects Simple Laundry 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 25.0th 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-2026-5257 is a SQL injection vulnerability in code-projects Simple Laundry System 1.0. The issue resides in the unknown processing of the /delstaffinfo.php file within the Parameter Handler component, where manipulation of the userid argument enables injection. Associated with CWE-74 and CWE-89, 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 lack of prerequisites.
The vulnerability is exploitable remotely by unauthenticated attackers with low complexity, requiring no user interaction or privileges. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption via crafted SQL payloads targeting the userid parameter.
