CVE-2023-5836Network attack vector

Authenticated SQL injection via unescaped id

Published Oct 28, 2023 · Updated Sep 9, 2024

SQL injection in SourceCodester Task Reminder System 1.0 allows remote authenticated users to alter database data via the delete-user function. The classes/Users.php?f=delete handler uses the id argument in a database operation without adequate SQL-safety controls, allowing injected input to change the query. Access requires a valid application account; the documented impact is database confidentiality, integrity, and availability loss.
