Deeper analysis

CVE-2026-6188 is a SQL injection vulnerability (CWE-74, CWE-89) affecting SourceCodester Pharmacy Sales and Inventory System 1.0. The flaw resides in an unknown function within the file /ajax.php?action=delete_sales, where manipulation of the ID argument triggers the injection. Published on 2026-04-13, it 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).

The vulnerability enables remote exploitation without authentication, user interaction, or high complexity. Attackers can send crafted requests to the affected endpoint, potentially reading limited data, modifying database contents, or disrupting service availability to a low degree.

Advisories on VulDB (including vuln/357110 and related CTI) and a GitHub issue (lingzezzz/lingze/issues/2) document the issue, noting that an exploit has been published and may be used.
