CVE-2026-7670
Published: 02 May 2026
Summary
CVE-2026-7670 is a medium-severity Injection (CWE-74) vulnerability. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 12.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-7670 is a SQL injection vulnerability in Jinher OA version 1.0, affecting an unknown function within the file /C6/JHSoft.Web.PlanSummarize/UserSel.aspx. The flaw arises from improper handling of the DeptIDList argument, allowing attackers to manipulate input and inject malicious SQL payloads. It is classified under CWE-74 and CWE-89, with a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its remote exploitability.
The vulnerability can be exploited remotely by unauthenticated attackers over the network with low complexity and no user interaction required. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, such as extracting sensitive data, modifying database contents, or disrupting service to a minor extent. An exploit has been publicly published and is available for use.
Advisories from VulDB and a GitHub issue detail the vulnerability but note that the vendor was contacted early without any response, implying no official patches or mitigations are available. Security practitioners should reference these sources for technical details and PoC exploits.
Notable context includes the public availability of the exploit, increasing the risk of active exploitation against exposed Jinher OA 1.0 instances. No vendor acknowledgment or remediation guidance has been issued.
