Deeper analysis

CVE-2019-25501 is an SQL injection vulnerability (CWE-89) in Simple Job Script, affecting the delete_application_ajax.php component. The flaw arises from improper handling of the app_id parameter, which allows attackers to inject malicious SQL code into database queries. Published on 2026-03-04, it carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high severity due to network accessibility and no authentication requirements.

Unauthenticated remote attackers can exploit the vulnerability by sending crafted POST requests to delete_application_ajax.php with malicious payloads in the app_id parameter. Successful exploitation enables manipulation of database queries to extract sensitive data, bypass authentication mechanisms, or modify database contents, resulting in high confidentiality impact and low integrity impact.
