3.7.1
CVE-2026-3026 describes a server-side request forgery (SSRF) vulnerability discovered in JEEWMS 3.7. This flaw resides within the UEditor component, specifically the /plug-in/ueditor/jsp/getRemoteImage.jsp file. Successful exploitation allows an attacker to initiate requests to internal or external resources on behalf of the server, potentially leading to sensitive data exposure or unauthorized access. Affected versions include 3.7. A patch is currently unavailable, requiring mitigation strategies.
The SSRF vulnerability in JEEWMS 3.7 allows an attacker to craft malicious requests through the upfile parameter in the /plug-in/ueditor/jsp/getRemoteImage.jsp endpoint. This can be leveraged to access internal resources that are not directly exposed to the internet, such as configuration files, database credentials, or internal APIs. An attacker could potentially scan internal networks for open ports and services, leading to further exploitation. The ability to make arbitrary requests on behalf of the server significantly expands the attack surface and increases the potential for data breaches and system compromise. This vulnerability is particularly concerning given its public disclosure and the lack of a vendor response.
This vulnerability was publicly disclosed on 2026-02-23. The lack of a vendor response raises concerns about the long-term security of JEEWMS 3.7. While no active exploitation campaigns have been definitively confirmed, the public disclosure and ease of exploitation make it a high-priority target for malicious actors. The vulnerability's SSRF nature aligns with common attack patterns, potentially making it a target for automated scanning tools. It is not currently listed on the CISA KEV catalog.
Organizations using JEEWMS 3.7, particularly those with exposed UEditor instances or internal services accessible via the JEEWMS server, are at significant risk. Shared hosting environments where JEEWMS is deployed alongside other applications are also vulnerable, as a compromise of one instance could potentially lead to lateral movement and impact other tenants.

Due to the absence of a direct patch for CVE-2026-3026, immediate mitigation steps are crucial. Implement strict input validation on the upfile parameter to prevent malicious URLs. Deploy a Web Application Firewall (WAF) with rules to block SSRF attempts, specifically targeting requests to internal IP addresses or sensitive endpoints. Consider using a reverse proxy to filter outbound traffic and restrict access to internal resources. Regularly monitor access logs for suspicious activity, particularly requests originating from the /plug-in/ueditor/jsp/getRemoteImage.jsp endpoint. After implementing these mitigations, verify their effectiveness by attempting to trigger the SSRF vulnerability with a controlled payload.
Aktualisieren Sie die UEditor-Bibliothek auf eine gepatchte Version, die die Server-Side Request Forgery (SSRF)-Schwachstelle behebt. Wenn keine gepatchte Version verfügbar ist, implementieren Sie robuste Validierungen und Filter für den Parameter 'upfile', um die Manipulation der URL zu verhindern und den Zugriff auf interne Ressourcen einzuschränken.
