Service interrupt via untyped pagination inputs
Published Aug 19, 2026 · Updated Aug 19, 2026
Denial of service in CMSJunkie J-BusinessDirectory before 6.2.3 allows remote attackers to interrupt service via crafted pagination parameters. Pagination handlers accept array and non-numeric request values such as limitstart[] and then perform arithmetic and list-query operations without strict typing or validation, which can raise PHP type errors or drive costly query handling. The issue is reachable over the network without authentication; published records describe availability impact, with no public evidence of code execution or direct data exposure.
