Is there a public PoC exploit available for CVE-2026-5564?

Yes, a public proof-of-concept exploit is available for CVE-2026-5564. Prioritise patching immediately. EPSS: 0.0%.

How to fix or mitigate CVE-2026-5564?

Within 24 hours: Identify all systems running Simple Laundry System 1.0 and assess network exposure (internet-facing vs. internal only). Within 7 days: Implement network-level access controls to restrict /searchguest.php to authorized users only, or take the application offline if not business-critical. Within 30 days: Migrate to a patched alternative laundry management system or discontinue use of this unmaintained codebase; evaluate database backups for evidence of unauthorized modification.

DescriptionCVE.org

A weakness has been identified in code-projects Simple Laundry System 1.0. Affected by this vulnerability is an unknown functionality of the file /searchguest.php of the component Parameter Handler. This manipulation of the argument searchServiceId causes sql injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

SQL injection in code-projects Simple Laundry System 1.0 allows unauthenticated remote attackers to extract, modify, or delete database records via the searchServiceId parameter in /searchguest.php. CVSS 7.3 reflects network-accessible attack with low complexity requiring no privileges. Publicly available exploit code exists (GitHub PoC published), significantly lowering exploitation barrier. No vendor-released patch identified at time of analysis. EPSS data unavailable, but combination of remotely exploitable SQLi with public PoC against an unmaintained open-source project indicates elevated real-world risk for installations exposed to untrusted networks.

Technical ContextAI

This is a classic SQL injection vulnerability (CWE-89) in a PHP-based web application. The affected component is the Parameter Handler in /searchguest.php, which fails to properly sanitize the searchServiceId parameter before incorporating it into SQL queries. SQL injection occurs when user-controlled input is concatenated directly into SQL statements without parameterization or escaping, allowing attackers to inject malicious SQL commands. Simple Laundry System 1.0 is a code-projects.org open-source project (CPE: cpe:2.3:a:code-projects:simple_laundry_system:*:*:*:*:*:*:*:*) likely used for small business laundry service management. The PHP codebase appears to lack prepared statements or input validation frameworks in this module, enabling trivial exploitation through crafted HTTP requests to the vulnerable endpoint.

RemediationAI

No vendor-released patch identified at time of analysis for Simple Laundry System 1.0. Code-projects.org does not maintain active security update channels for contributed projects. Organizations using this software should implement immediate compensatory controls: restrict network access to the application admin interface via IP allowlisting or VPN-only access, deploy web application firewall rules to block SQL injection patterns targeting the searchServiceId parameter, or discontinue use in favor of actively maintained laundry management software. For organizations with development resources, manual code remediation is required: refactor /searchguest.php to use PHP PDO prepared statements with bound parameters for the searchServiceId input, implement input validation to restrict searchServiceId to expected alphanumeric formats, and conduct comprehensive code review of all Parameter Handler components for similar injection flaws. The GitHub PoC at https://github.com/Kazamikazu/Ksec/issues/2 provides exploitation details that can inform defensive testing. VulDB entries at https://vuldb.com/vuln/355334 contain additional technical context. Given the lack of vendor support, migration to a supported alternative is the most sustainable long-term remediation.
