CVE-2022-50997Known exploitationNetwork attack vector

Database disclosure via unsanitized id parameter

Published Aug 11, 2026 · Updated Aug 11, 2026

SQL injection in Weaver E-cology 8.0 and 9.0 allows remote attackers to read backend database data through an unauthenticated HTTP request. The HrmCareerApplyPerView.jsp endpoint inserts the id GET parameter into a Microsoft SQL Server query without sanitization, allowing a UNION payload to control the query. No account or user interaction is required, and a single crafted request can disclose arbitrary database data.
