Summary
CVE-2026-96428 is a critical, unauthenticated SQL injection vulnerability in Flowring Technology Corp’s Agentflow 4.0 web portal. The flaw resides in the /WebAgenda/SMBAjaxAutoComplete.do API endpoint, which fails to sanitize the words parameter before using it in a SQL query. With a CVSS score of 9.3, remote attackers can execute arbitrary SQL commands without any authentication or user interaction, fully compromising the confidentiality, integrity, and availability of the underlying database.
Technical details
- Root cause: The
wordsparameter passed to the/WebAgenda/SMBAjaxAutoComplete.doendpoint is concatenated into a SQL statement without proper input validation or parameterization (CWE-89). - Trigger conditions: An attacker sends a crafted HTTP request to the vulnerable endpoint with malicious SQL payloads embedded in the
wordsparameter. - Attack vector: Network-based, requiring no authentication (PR:N) and no user interaction (UI:N), making it exploitable directly over the internet against exposed instances.
- Impact: Successful exploitation allows execution of arbitrary SQL commands, which can lead to unauthorized data disclosure, modification, or deletion, and potentially full compromise of the backend database supporting the Agentflow application.
Affected software
- Flowring Technology Corp Agentflow 4.0, all versions prior to the fix dated 2025/08/08.
Severity
- CVSS Score: 9.3 (Critical)
- CVSS Vector:
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Mitigation and recommended actions
- Immediate: Upgrade Flowring Agentflow 4.0 to the version released on or after 2025/08/08, which addresses this SQL injection flaw.
- If no patch can be applied immediately: Restrict network exposure of the
/WebAgenda/SMBAjaxAutoComplete.doendpoint (e.g., via firewall rules, VPN, or access control lists) so it is not reachable from the public internet, and deploy a web application firewall (WAF) rule to detect and block SQL injection patterns targeting thewordsparameter until the upgrade can be completed.
