CVE-2026-2954 is a medium-severity Injection (CWE-74) vulnerability in Ujcms Ujcms. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.7th 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 AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-2954 is an injection vulnerability (CWE-74, CWE-707) in Dromara UJCMS version 10.0.2. The flaw affects the importChanel function within the ImportDataController component, specifically at the endpoint /api/backend/ext/import-data/import-channel. It stems from manipulable arguments driverClassName and url, enabling injection attacks.
An attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. The CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) indicates that successful exploitation results in low impacts to confidentiality, integrity, and availability.
Advisories from VulDB note that a public exploit exists and the vendor was contacted early for disclosure but provided no response. No patches or official mitigations are referenced in the available sources, including the Yuque documentation link.
The exploit's public availability increases the risk for unpatched Dromara UJCMS 10.0.2 deployments, with the vulnerability published on 2026-02-22.

Directly requires validation of driverClassName and url inputs to the import-channel endpoint, blocking the CWE-74 injection described in the CVE.
Enforces access restrictions on the /api/backend/ext/import-data/import-channel function so that only authorized subjects can reach the vulnerable importChanel code path.
Restricts the system to only approved data-import drivers and connection URLs, eliminating the ability to supply arbitrary driverClassName or url values that trigger injection.
