Technical Analysis
The vulnerability in banq jivejdon arises from improper control of interaction frequency on the /account/smsVRAction endpoint handled by SmsQQAction. This endpoint does not enforce rate limiting for unauthenticated users, enabling attackers to repeatedly send SMS messages.

The affected versions span from commit e0306088 through commit ee67a65e. The CVSS 4.0 base score is 6.9, indicating medium severity.
Potential Impact
Attackers can exploit this vulnerability to send unlimited SMS messages without authentication, potentially harassing arbitrary phone numbers and causing financial loss by exhausting the operator's Tencent Cloud SMS balance. There is no indication of direct compromise of system integrity or confidentiality from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing external rate limiting or monitoring on the /account/smsVRAction endpoint to prevent abuse.
