CVE-2026-45412: CWE-918: Server-Side Request Forgery (SSRF) in 1Panel-dev MaxKB
CVE-2026-45412 is a Server-Side Request Forgery (SSRF) vulnerability in the open-source AI assistant MaxKB by 1Panel-dev. Versions prior to 2.9.1 allow authenticated users to supply arbitrary URLs via the work_flow_template.downloadUrl parameter, which the server fetches without validation or internal IP filtering. This can lead to unauthorized server-side requests. The vulnerability has a CVSS 4.0 score of 6.3 (medium severity). A fix is available in version 2.
AI Analysis
Technical Summary
MaxKB versions before 2.9.1 contain an SSRF vulnerability (CWE-918) in the work_flow_template import functionality. Authenticated users can specify arbitrary URLs in the downloadUrl field, which the server fetches without validating the URL or filtering internal IP addresses. This allows attackers to make server-side requests to potentially sensitive internal resources. The vulnerability is addressed in MaxKB version 2.9.1.
Potential Impact
An authenticated attacker can cause the MaxKB server to make arbitrary HTTP requests to external or internal network resources. This may expose internal services or data accessible only from the server's network. The CVSS score of 6.3 indicates a medium severity impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade MaxKB to version 2.9.1 or later, where this SSRF vulnerability is fixed. Since the vendor advisory confirms the fix in 2.9.1, applying this official update is the recommended remediation. No additional mitigation guidance is provided or required.
