CVE-2026-62362 Details
Description
PeerBanHelper automatically blocks unwanted, leeching, and abnormal BitTorrent peers using customizable and cloud rules. From 5.0.0 until 9.3.15, the /api/statistic/analysis/field endpoint accepts a crafted field query parameter from an authenticated user and passes it to countField or sumField. The mapField() method forwards unrecognized field names without sanitization, so unrecognized field names are interpolated into SQL through ${field} across the SQLite, MySQL, and PostgreSQL mappers. Successful exploitation can read all data in the PeerBanHelper database. This issue is fixed in version 9.3.15.
A SQL injection vulnerability has been identified in PeerBanHelper versions 5.0.0 prior to 9.3.15. The issue arises in the '/api/statistic/analysis/field' endpoint, where a crafted 'field' query parameter from an authenticated user is passed to 'countField' or 'sumField' methods without proper sanitization. This flaw allows unrecognized field names to be interpolated into SQL queries, enabling attackers to manipulate the SQL execution and potentially read all data from the PeerBanHelper database. The vulnerability has been patched in version 9.3.15.
Users are advised to update PeerBanHelper to version 9.3.15 or later, where this vulnerability has been fixed.
