Detailsinfo

A vulnerability was found in PBH-BTN PeerBanHelper up to 9.3.14. It has been classified as critical. Affected is the function mapField of the file /api/statistic/analysis/field. The manipulation of the argument field with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-62362 since 07/14/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1505 by the MITRE ATT&CK project.

Upgrading to version 9.3.15 eliminates this vulnerability.
