CVE-2026-55871: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in mayerbalintdev GYM-One
Description
GYM One is open-source gym management software for fitness centers, personal trainers, and sports clubs. Prior to 1.4.1, GYM One's admin/users/index.php concatenates the search_name and search_email GET parameters into both the user-list query and the COUNT query used for pagination without prepared statements. An authenticated administrator can inject SQL through either search field to read data from arbitrary tables, including user information and password hashes. Depending on database permissions, the same injection may also permit filesystem writes. This issue is fixed in version 1.4.1.
