CVE-2026-107830 · Severity: medium · CVSS 5.3 · Published 2026-10-08

Jivejdon is a web-based notebook and collaboration platform that integrates SMS verification for user account creation. This vulnerability allows attackers to send unlimited SMS messages through an unauthenticated endpoint without rate limiting, enabling them to harass phone numbers and drain the application operator's Tencent Cloud SMS budget. An attacker can load the account creation page to set session variables, then repeatedly trigger SMS sends to arbitrary numbers.

Technical details

The /account/smsVRAction endpoint handled by SmsQQAction lacks rate limiting and is accessible without authentication. Attackers can exploit session manipulation via the newAccount.jsp page to set required attributes, then make rapid requests to the SMS endpoint to send unlimited messages. This allows cost exhaustion and harassment attacks against arbitrary phone numbers.
