CVE-2022-2776Network attack vector

Remote denial of service via delete_user input

Published Aug 11, 2022 · Updated Apr 15, 2025

Denial-of-service flaw in delete_user.php in SourceCodester Gym Management System allows remote attackers to interrupt service via crafted delete_user input. The affected function mishandles the attacker-controlled delete_user argument, but the specific resource operation causing the interruption is not publicly documented. Remote reachability is reported, while required privileges and deployment conditions are not documented, so the bounded impact is service availability.
