CVE-2026-5540
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been found in code-projects Simple Laundry System 1.0. This vulnerability affects unknown code of the file /modifymember.php of the component Parameter Handler. Such manipulation of the argument firstName leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in Simple Laundry System 1.0's modifymember.php file. The firstName parameter is not properly sanitized, allowing remote attackers to inject malicious SQL queries. This is a classic SQL injection flaw in the Parameter Handler component.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Simple Laundry System installation and versionLocate the application directory and check for version indicators such as version files, headers in PHP files, or admin panels that display version informationAffected if The installed version is Simple Laundry System 1.0 or earlier without patches applied
-
Verify modifymember.php existsLocate the file modifymember.php in the web application's directory structure, typically under the web rootAffected if The file modifymember.php is present in the application
-
Examine firstName parameter handling in modifymember.phpOpen modifymember.php and search for occurrences of the firstName parameter; inspect how it is used in database queries (look for direct string concatenation or lack of prepared statements)Affected if The firstName parameter is used in SQL queries without parameterized queries or prepared statements, indicating direct string concatenation into the query
-
Confirm lack of input validation on firstNameReview the code handling firstName for sanitization functions such as htmlspecialchars, mysqli_real_escape_string, or other validation routines before database executionAffected if No input validation or sanitization functions are applied to the firstName parameter before it is included in SQL queries
-
Test for unauthenticated access to modifymember.phpAttempt to access modifymember.php directly via HTTP request without providing authentication credentialsAffected if The endpoint is accessible without authentication and accepts the firstName parameter in the request
The system is affected if it runs Simple Laundry System 1.0 with modifymember.php present and the firstName parameter is handled via direct SQL concatenation without prepared statements or input validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataFix the modifymember.php file by implementing parameterized queries (prepared statements) for the firstName parameter and any other user-supplied inputs. Apply input validation and escaping as defense-in-depth.
