Deeper analysis
CVE-2026-5564 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple Laundry System 1.0, published on 2026-04-05. The flaw affects an unknown functionality in the file /searchguest.php within the Parameter Handler component, where manipulation of the searchServiceId argument enables injection. The vulnerability 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 low complexity.
Remote attackers require no privileges or user interaction to exploit this issue, allowing initiation over the network. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or disruption via injected SQL queries. A public exploit is available, increasing the risk of attacks.
